Changed internet plans now can't conenct to xfinity wifi hotspots

While I appreciate the help Marty, this is an issue with public wifi hotspots, not my (personal) equipment. I was able to reach out to support over the phone finally and was told that they will resolve whatever the issue is on their end to fix my problem.

Anyone who comes across this after having changed their plans because of the new price and data package all I can suggest is to call comcast directly and get a hold of a person directly. This seems to be something happening when switching to the new plans that xfinity needs to fix.

I have same problem albeit I didn't have any changes to my plan.  I first noticed it probably 2-3 months ago but I don't really depend on it so just ignored it.  Began engaging Comcast to fix it and its been very frustrating.  Today they are sending somebody out to "fix my degraded signal issues in my house" as a first step.  Which makes no sense.  Even if I power off and disconnect my home cable modem, I should be able to go down the street and connect to Xfinity hotspot.  But at least it appears that I've got the attention of a higher up tech so I'll keep pursuing.   I have seen other postings where people said they either switched from their own cable modem or switched to Comcast provided cable modem and the problem was resolved.  Given that situation I'm guessing there's a side-effect from adding a new cable modem that tickles their system to inadvertently fix the true issue.  

Note that the error message in the app is:  "Xfinity WiFi is not available with your tier of service."

In addition to getting this error when attempting to connect to a Xfinity Wifi Hotspot, if you try to configure the app to automatically connect to Xfinity Wifi Hotspots you get a similar error, i.e.  "You don't have access to Xfinity WiFi hotspots. This type of account does not have access to Xfinity Wifi hotspots."
