Hi! Since downloading Win 11 a few weeks ago into my 1.5 yr old Lenovo laptop, a new problem has been occurring only in Facebook and only as an Admin in three private groups in Facebook. When I try to post in those groups, the pale blue Post button is AWOL. I can post in any other Facebook field, just not in my own groups. This never occurred in Win 10. Pretty inconvenient for an Admin/Moderator. (I can answer others' posts in those groups; just can't post independently) I happened to try running Firefox in Test mode and the problem went away, but that Test mode does away with Facebook Container. Alternately I can run Facebook in either MS Edge or Chrome, which also ends the problem, but I loathe both so those aren't real options. So far I seem to be the only person reporting this bug. What can you great people suggest as a fix? Huge thanks from a non-Geek.
