I have put off asking the question for some time because I know it is vague and terrible to debug so I welcome your help refining the question as well as potential solutions.
A range of certain apps will report no internet connectivity and get stuck in that state no matter how good my WiFi and/or mobile data connection or if I force stop and/or clear their cache. So far:
- whatsapp (i get the clock symbol)
Normally only one of these at a time, sometimes two. Never all! (so not just general connectivity issues). I ignore them for a day or two and they never recover connectivity. Chrome is never affected (yet) and I still get push notifications for said apps.
I am technical and have pondered dodgy dns but apps get in this state on and off Wi-Fi which should mean different dns servers, not just a quirk on my home network. I don't use a mobile VPN. I do have a work profile. My phone is a standard build Samsung S10 that behaved normally for over a year until recently.
Drives me mad because all advice out there is for fixing general/global connectivity as people always complain about that and turn it off and on again is a good solution for any single app getting into a funky state but this feels dumb, like the OS is caching/blocking/blacklisting something and I kinda wanna blame samsung or put on a tin hat and blame the government... yeah I am mocking myself now :)
So, any suggestions?
Ahhh! I just had two messaging apps go quitely into this offline mode. Toggle wifi, nothing. Toggle flight mode, nothing. I restart and instantly these send and retrieve messages. If i cannot relay on my phone to communicate it is useless!
