Mobile app not able to sync history

[karmic valley]

I have updated my app and now I can't synchronize my chats. I did relog and now there is no older chats at all...
Android ONE UI 6

Hello Valentino! Do you have a VPN app installed on this device, or perhaps an adblocker app of some kind?

[karmic valley]

Nope, I have no VPN it was working fine yesterday.

[pulsar basin]

And no adblocker app either?

[karmic valley]

Correct, I don't have that too

Are you familiar with the process for force closing an app clearing its cache in Android's "App info"? If so, can you try:

• Turn off WiFi/connect to cellular network
• Force close/clear app cache
• Reopen app on your cellular network
  ...to see if the network change makes any difference for you?

[karmic valley]

Same result

Will try restart my phone

Restart also not helping.

And just to double check: you were able to try the force close/clear cache step in between as well?

[karmic valley]

Did that before restarting phone, now reinstalled app, but still no luck.

Has the WiFi stayed off since force closing/clearing app cache? The thing I'm trying to troubleshoot with that is whether there's some mismatch happening with your WiFi network specifically, so force closing/clearing the cache after disabling WiFi, and keeping it off, is the specific troubleshooting step I'm suggesting here. Is that what you're saying you've done? Thanks for your patience 🙂

[karmic valley]

Correct, there was no WiFi possibility at the moment I have done those steps.
Everything was done on mobile data.

Okay, thank you for confirming! Can you double-check your DNS settings in Android's settings? For me, it's Settings app, Network & internet, Private DNS. What's this set to for you?

[karmic valley]

DNS is set on automatic

All right, so no VPN installed, no adblocker app installed, app force closed/cache cleared, different networks tried, phone rebooted, app uninstalled and reinstalled, no custom DNS settings... I'm stumped! Three more "long shots" to ask about:

• Do you have any other kind of app installed that might be filtering your traffic in any way?
• As a test, can you try changing your DNS settings to something like Cloudflare's DNS, followed by another force close/cache clear? If it's related to DNS glitches, maybe forcing it to use a certain DNS will help it clear up.
• Are your date and time settings correct? Setting themselves automatically? Sometimes a mismatch there can cause network issues.
