Mail reverting to old signature
I recently updated to Mac OS Big Sur 11.4, now my mail account keeps reverting to an old email signature. Have deleted the old and constructed a new signature five times, but if I close mail and reopen the new signature is gone and old one is back in use.
MacBook Air M1 2020, Mail version 14.0.
Thanks for any help resolving!
MacBook Air (2020 or later)
