endless redirection loops on accessing hackpad document

hi, I think this is an annoying bug and unfriendly experience.
I met that a couple times, it's easy to reproduce this bug.
Suppose you have two gmail accounts (one private and one company), A and B;
You get invited from account A, but when you access the link with B account, you get redirected loops without a clue... it seems like hackpad isn't functioning at all.
At least, the system should catch this issue and inform user that: he, are you using the correct invited email account?
