facebook messenger not syncing

Hi all! I just got a new galaxy s6 and searched for a solution to my problem before posting this but couldnt find anything. Facebook messenger (the separate application) does not seem to want to sync completely. Messages sent and received on desktop are not seen at all on the messenger app but are seen in the regular facebook app when u navigate to the messeges tab. Also, messages sent on the messenger app appears when i look at it on the desktop. How can i fix this so the messenger application syncs correctly with facebook?

Google Calendar Not Syncing

I recently switched from ios back to android on my Note 5. The problem I'm having is syncing over my Google calendars to this phone. My wife has an iPhone 6 and I can't seem to see any of her events on her Google calendar on my phone. I've tried several different apps and dug through all the settings, removed her Google account, added it back in, restarted my phone. Everything I can think of, I've tried and still her Google calendar won't sync to my phone.

Has anyone ever ran into this before or have any other ideas?

My last option to try would be to sign back into my icloud on my iPhone 5s that I still have and use samsung smart switch. Has anyone ever used this app and had success with it?

Contacts stopped syncing after update

After the latest firmware update, my watch shows "Contacts Temporarily Unavailable." It's been showing this for a couple days now. Anyone found a fix?
Thanks!
