Unable to update Procreate on main account after joining beta test with secondary account

A few days ago I joined Procreate beta and I had a secondary account (which does not have procreate on it) logged into appstore. Today I saw that Procreate 5.4 is available on appstore, so I logged into my main account (the account I bought procreate with) and tried to update it. I tried multiple times and got the same message. Then I logged back into the secondary account and removed procreate from testflight, and I tried to update again with my main account in appstore, but it still did not work.
