Angry! Two seperate accounts - cannot setup - because cannot link two accounts to amazon - so share an account

This really angers me - I setup ring - then all is working - I invite my wife - we setup her account - then we find out we cannot link the account to amazon - so she has to use my account What the #@$#$$#! So now I have to disable 2FA on my ring account because she will not be able to receive my texts with the code. this is idiotic - I'm about to box up all this ring #@$@#@#
