are there any known problems, using groups.google.com for mail?
since 2026-05-01 I did not receive any mail via google groups any more. They show up in the list's archive - but I never received an e-mail copy of those, as before.
No, they are not in my junk mail folder.
I have seen former similar reports, such as https://www.reddit.com/r/gsuite/comments/1cmx9nw/google_group_emails_not_getting_delivered_any/?tl=de , but no solution.
Edit: one of the members has a read triangle - but not me.
