Unable to install Ratio Pro after factory reset of phone

My Pixel 4 XL tells me to go to members.blloc.com and remove my previous phone (same phone, just pre-reset) to use my invite code. That website does not let me log in and tells me that an email has been sent to me. Of course, this is not true, and many refreshes and retries later I’m at a loss for what to do.

There seems to be a problem with the members site. Ensure that you type the email ID with the same case while you signed up (usually the forst letter being in caps).

The team is looking into it.
