favorites disappeared from cable box but are still available in the app

I have the same issue here on set top box - no favorites but streaming app shows my favorite channels list.  Xfinity needs to send a notice on the tv box to all customers and then push the update correcting this.  What is the timeframe for this correction?

Same issue this morning, all favorites gone. Fix this please. Diamond level user.

After spending an hour last night on the phone with Xfinity L1 support to no avail I figured this out this morning. Here is the true fix.

1. Basically what they have done in their infinite wisdom is deleted your favorites. And since your default view is probably set to favorites that’s why you’re getting the pop-up and no guide to display. The fixed is as follows, but it takes a bit.

2. Go to settings, preferences, and set your default view to either all channels or all HD channels as I did. Then your guide will work.

3. At this point, your guide will work well displaying all channels. So reset all of your favorites which will do it for all TVs in your house.

4. Then go Back to settings, preferences, and set your default view back To display favorites.

THIS WORKS!!!!!!!

Just got off the phone with "Mark" in customer service who after confessing that this was a system issue with Comcast/Xfinity thanked me for being a Diamond member and tried to upsell me faster internet despite my repeated statements that all I needed or wanted was for them to fix the favorites issue. Typical Comcast "service" [Edited: "Profanity"]. Looks like we're stuck adding favorites one by one as described above. 11 years a Comcast customer even though they continue to try my patience on the regular. As a practical matter finding a different provider, then changing everything (TV, VoIP and Internet) would be more of a headache than putting up with Comcast's incompetence and indifference.

Come on Xfinity, you broke it you should fix it. The data is still out there as everyone can see their favorites in the streaming app but not on the set top box. I really don’t want to spend an hour adding them back in. 

Another lesson in why we test before we push to prod, right Xfinity?  Who wrote your test scripts/test plan?  Or do you even have QA anymore? 

Lost mine today!                             

Any solution?                

Like others, favorites gone from box.  At first glance, I thought my favorites remained in streaming app, but upon closer scrutiny, only some remained.  Dozens have disappeared.

It's going to be a [Edited: “Profanity”] to recreate my original favorites, and I wish I could feel more confident that if I bother to do that, they won't be all [Edited: “Profanity”] up again by tomorrow.

I went online and requested a System Refresh. Favorites are now back. Go to their website, select Contact and Support, then Fix An Issue, then choose System Refresh. Took about 5 minutes or so, then voila. 

I hadn't gotten around to doing anything about it, and just now notice that everything is fixed.  All my favorites are back via both the box and streaming. 👍

Same problem for 2 days. Input all favorites again but the other ones that are not favorites are there also
