I had this sometimes with v2, that some accounts would keep giving a warning that email wasnt validated
Upgraded to v3 and it seems to be a bigger problem because you cant ever get past that message.
For certain users the validation email never arrives to inbox or spam box.
Todays example was with a gmail account, is that a known problem?
Probably not related but theres a long list of errors in error log, here are first few, what might have caused this?
