@emeritaacuity0u could you clarify more detailed steps to reproduce the problem? How long is the internet down when this problem occurs?

Also we need to get the app logs.

Here's what we need you to do:

  • Open Settings --> General --> Turn Advanced mode on --> Advanced settings --> Turn Debug logs switch on;
  • Reproduce the issue and remember the exact time when it happened;
  • Disable "DNS Privacy";
  • Open the settings --> Support --> Export logs;
  • System popup will be opened --> Choose "Mail" app
  • Enter apple@adguard.com as a recipient;
  • Mention this issue number in the subject and add the time the issue was reproduced at.

Given how intermittent it is, it's impossible for me to reproduce. I can confirm this issue isn't related to the network switching between mobile/wifi at the very least.

I'll reply back when it happens again.
