(Ops, I can uninstall lol, using Gmail until app is fixed)
First off, my starting version: 22.214.171.124 (latest update released on Aug 5th). The play store was showing I was up to date (even listed the same version).
I uninstalled Samsung Email and reinstalled an older version from the Galaxy Store, 126.96.36.199(last updated on Aug 2nd). But it still had the same issue.
The Play Store showed it needed updated and I updated it to 188.8.131.52. (Now showing last updated July 28th)
Problem has been fixed!
