I wanted to advise you that of last night we have released fixes for our True Key Chrome, Firefox extensions. We have also submitted the fix for the True Key Edge extension but it is pending to be approved by Microsoft, shortly after it is you should get that fix as well.
Please check that instant login is now working as expected, if you see anymore issues let me know. I have tried replying individually to all of you that have reported this issue to me but in case I haven't with one of you, I think this is the best way to inform everyone.
I am sorry for the issues you have experienced with the instant login but glad the fix is out ahead of the weekend.
