POP3 authentication failure

POP3 authentication failure

Update 19/02//21 - still no reply

I just contacted support via the contact form - this is just to inform the forum of what is going on + keep track of what and when I wrote because Zoho doesn't seem to deem it necessary to send a copy of the support request to my account... 

After years of working fine, all of a sudden authentication failure with Yahoo account; when trying to re-enter and save (the same/unchanged) credentials - no change. Started 10 February and persists

Tried to create new POP3 account to compensate for the above problem - this time with AOL: cannot even create it - getting "[SYS/Temp] error - try again later" all the time.
