Issue with Xfinity/Comcast Email Downloading on new iPhone 16 Plus – iOS 18.5 and new iPad A16

I saw in this forum where others were having the same issue I am experiencing but I didn’t see a resolution.

I purchased a new iPhone 16 Plus on 03/24/25 at the local Verizon store.  The manager there actually did the download from iCloud and everything came over perfectly that was on my old iPhone 7.  All my existing emails and folders that were on my iPhone 7 came over perfectly as well regarding content.  While there, I never looked to see how new emails would behave until I returned home that evening.  When I did, the Comcast emails using the Apple iOS Mail App on my new iPhone were and are still extremely slow connecting and downloading.  The behavior is as follows – which is extremely slow:  Connecting; Checking for Mail; Downloading; Updated Just Now and takes forever for the content of the email to display.

 

I have gone back to Verizon, the Geek Squad, Apple Genius Bar in person twice (which instantly ran a diagnostics on my new phone to make sure functioning correctly) and worked with Apple Tech Support Level 2 since March 24th.  Today is 06/23/25 and the issue still isn’t resolved.  Everyone has been terrific in trying to resolve.  Long story short; everything has been tried on my iPhone already mentioned in this forum plus several other things not mentioned trying to resolve my issue.  E.g. Ran diagnostic; dropped email account; checked iCloud settings; checked numerous iPhone settings; deleted Apple mail app and readded; did a ‘reset’ of network connections; dropped WiFi and readded; tried WiFi only and then cellular only;  and these are only a few things tried.  My issue has been worked on weekly with the assistance of some one from each of these businesses. This whole issue has been a buzz kill regarding enjoying my new iPhone 100%. I never had this issue with my iPhone 7.  Worked great.  I only got rid of it because it was no longer supported by Apple.  Comcast email always worked correctly.  Finally at the suggestion of a technical friend he told me to add my Gmail email account to my new iPhone and see what the email behavior was.  Gmail worked and works perfectly and as expected.  Everything is instantly downloaded and available to view.

 

Finally I was connected to an Apple Tech Support Level 2 last week and he stated right up front that he would not hang up until we had an action plan/next steps for me.  He saw everything I tried that I reported in my initial Apple ticket and what prior Apple Tech Support senior technicians had already tried.  He stated to me that there wasn’t anything else to do that hasn’t already been tried to resolve my email issue – by anyone.  So no doing the same things again and expecting different results. He stated this was an Xfinity/Comcast issue; which is what Verizon, Geek Squad, Apple Genius Bar, etc had stated previously as well.  He mentioned this forum to me and saw others had the same issue I was experiencing but couldn’t see the resolution if there was one. 

 

I told the last Sr Apple Tech Support Level 2 tech that I had contacted Xfinity/Comcast Customer Service already and early on but only was able to talk to their first line of support/customer service; which they told me right off this issue is an Apple issue and Xfinity/Comcast couldn’t help me because the web version of my Xfinity/Comcast email was working correctly.  And they have nothing to do with the Apple iOS Mail app/icon on my new iPhone. They didn’t want to have any conversation about by new iPhone Xfinity/Comcast mail issue. I told the Sr Apple Support level 2 tech that my Gmail email worked correctly and he said that Xfinity/Comcast email should then as well; as Apple doesn’t discriminate only against Xfinity/Comcast and not Gmail. He told me to state my issue in this forum and then contact Xfinity/Comcast and ask for a level 2 technical person to address what is happening with my Xfinity/Comcast email.  I am a 32 years long time customer of Xfinity/Comcast; but this didn’t matter to the Xfinity/Comcast customer service person I spoke with.  So here I am at this forum looking for assistance. Everyone I have worked with to date already has stated they don’t have access to Xfinity/Comcast servers or server settings, etc.  They all have stated this is an issue with Xfinity/Comcast.  And now I see by the forum that I am not the only one with this issue.  I imagine there are numerous others also that haven’ reported it; and are just living with it versus the hassle of trying to get it resolved.

I have the same issue with my new Apple iPad 16. 

 

I am hoping someone has a resolution of how exactly their issue like mine was resolved.  Thank you.
