Wow companion app stuck at syncing

4 days back I am able to use the wow companion app with no issue. But after that I cannot use the app only for one of my character in OC server. I tried using the app for my alts but I have no issue with them.

Note: I already tried doing the following but to no avail:

  1. ensuring that I’m in the correct region (America’s and Oceania)
  2. reinstalling the application
  3. clearing cache
  4. restarting my phone
