Hello,
It is strange situation because we do not get reports about such problem from other our customers, and there is no this problem on our test sites.
It seems to have changed wp-admin access, we can’t log in now. Please provide correct access to site where the problem persists. If your site is live, create a staging site (a full copy of the live site, so we can do tests there).
Also, record a video of the problem, so I can pass it to our dev team.
Regards
