Until today (29th Oct) my Pegasus Mail (v4.81 public beta of Jan 2023) configuration has functioned perfectly when accessing my several Gmail accounts using the OAUTH2 capability that David introduced into PMail, but as of this morning every attempt to access any of my accounts on Gmail's POP3 server results in an 'Invalid credentials' error.
Included below is a sanitised version of the error message I get when I try to access the Gmail mailbox for one of my usernames; I've hidden my IP address and also the lengthy string which is presumably associated with the OAUTH2 dialogue.
14:19:59.845: --- 29 Oct 2023, 14:19:59.845 ---

Is anyone else experiencing issues with accessing Gmail today? I definitely haven't changed anything in my PMail configuration so can only surmise that something has happened at the Gmail end...
Thanks in advance for any guidance and advice
