Tried to setup the latest version of K-9 mail with Gmail, once I sign into Google, it says that the application is blocked. Tried with Fairmail (Google Store version) and it works.

Version 8.1 installed from F-Droid is working with GMail accounts for me.
Are you using consumer GMail or Google Workspace GMail that may have allowed apps managed by a company administrator?
I’m using consumer Gmail, will try the F-Droid version and report back

Tried the F-droid version. Same problem
Can you post a screenshot of the error screen?
When the app was requesting permission to access your Google account, did you press the deny button at some point?
Go to https://myaccount.google.com/connections and remove your connections to “Mozilla Thunderbird Email”. Then try to set up the account again in the app.

No I haven’t.
The thing is that I have been using Maildroid Pro for over a decade.
It stopped being able to connect to Gmail a little over a week ago, but I didn’t notice until now.
It gave me the same error message above, even when I removed the account and tried to re-add it.
Thinking it was just about the developer no longer updating it, I found you guys as a potential replacement… But it’s throwing up the same error, so something has happened on Google’s end.
I went to the link you provided, and “Mozilla Thunderbird Email” is not even listed.
What’s the authentication method? Normal, OAUTH2?
Normal likely won’t work with Google - they disabled application passwords couple months ago.

The default when K9 is downloaded: OAUTH2.
When trying normal, this is the result:
EDIT - Only allowed to reply 3 times in a thread:
So this block is account-specific and their likely doing A/B testing?
I give up… I’ve been using this gmail account for work all these years, but I guess I have to go back to Yahoo then.
Thank you for looking into it!

It’s possible that the OAuth error is displayed because Google decided our “OAuth application” needs re-verification. We’ve started this process a while ago. But it’s still ongoing.
This problem doesn’t seem to affect all users. I was able to sign-in using OAuth with all my Google accounts.

FWIW, you can still set up an app-password with google at:
https://myaccount.google.com/apppasswords
so I have no reason to believe they don’t still work.
You do have to have 2fa enabled for your account in order to be able to create them.
