(Updated to say maybe you need a separate hot issue for Identity Safe since I am seeing so many posts about the vault)
I believe this is part of the same issue. After 22.5.0.124 I am unable to open the vault from the Norton Toolbar or from Norton Security. The message says it has timed out, try again later.
I _am_ able to open the vault using the online link, but that doesn't autofill anything.
I believe something broke in the update for Identity Safe or at least its underlying use of communication protocol.
