Hello All,
could you share the way you are using Facebook messaging on Mac OS? After Facebook seems removed the Messaging option from m.facebook.com and messenger.com is not the best place for have convenient messaging experience, I'm a bit unsure how to reach this feature on Mac OS 10.15.7. AFAIK the Stand-alone Messenger app on Mac OS also has accessibility issues. Tried to search for any information about why the Messaging was removed from the mobile site or whether was this fully removed and not disabled, but found nothing related.
Thanks
