Recently upgraded my Ipad Pro to IOS 26.6.1 and now have issues with conversations in FB. I do not use the FB app, I use safari with facebook.com. Generally use marketplace and start conversations with buyers and sellers, with messenger through FB. Recently when I go back to a conversation a day later some of the conversation is gone. I have tried logging out, power off, ensured disappearing messages is off. In some cases I go into the conversation the next day and the missing info is there but other lines are gone now. Anyone experience this?
