The subject basically explains it all. When the app is enabled so my Android uses 126.96.36.199 all updates via Google play are forever pending, but never start. If I pause the app downloads for updates start instantly. This only started recently, so I am not sure what has changed.
Same problem here.
I had over 30 apps pending, and have been for weeks.
Disabling 188.8.131.52 allowed updating to resume.
I have advanced settings>full tunnel enabled.
I eventually found a workaround, but only by going into the app preferences and having it specifically disable when the Google Play app is in use, otherwise it is impossible to update Android apps normally. It made me wonder if Google was doing this because the DNS wasn’t their own or if Cloudflare simply hadn’t thought this through.
