Cloudflare (DNS 1.1.1.1) causing login and item add/save issues

I started getting errors on my Android phone during logins and saving new or updated items. This usually resulted in an error of “Unexpected Error” or “The action was canceled”. This was also usually fatal to the action, but sometimes, a new item or update would be successful despite the error. I finally decided to re-install and thought I was stuck until I decided to try pausing cloudflare (1.1.1.1) DNS resolution. The issue went away immediately.

Please advise if this is Bitwarden or Cloudflare…

If the issue is gone after you changed one thing only I would call this the culprit.
