Q: Apple Watch can't open Facebook Messenger!

Hi

If you have not yet done so, it may help to update your iPhone and Apple Watch to the latest software versions (presently iOS 9.2 and watchOS 2.1):

• To update your watch from a software version prior to watchOS 2, your iPhone needs to be running iOS 9 or later.
• Update the iOS software on your iPhone, iPad, or iPod touch - Apple Support
• Update the software on your Apple Watch - Apple Support

Then try the following steps, trying to open the app after each:

• Place your Apple Watch on its charger with power connected and also connect your iPhone to power.
• On your iPhone: open the Music app and start playing a song (through your iPhone speakers is fine).
• On your iPhone, in the Watch app, go to: My Watch (tab) > scroll down and tap on the name of the app that won't open > turn off the option for Show App on Apple Watch > pause for a few moments > turn the option back on off, then back on.

If that does not resolve the issue, next unpair and re-pair your watch:

• The Watch app on your iPhone takes watch backups automatically, including a fresh one when unpairing via the app.
• Choose to restore the watch (Restore from Backup) when offered the option during set up. Most data and settings will be restored, with some exceptions (eg Apple Pay cards, passcode).
• Unpair your Apple Watch and iPhone - Apple Support
• Set up your Apple Watch - Apple Support

This is what worked for me... 

1. On your phone, open Messenger.

2. Go to Settings at the lower right of the screen

3. Go to Apple Watch

4. Change one of the "Default Replies" to anything you want

5. Go back to settings by touching "<Settings"

6. Go to Apple Watch again

7. Delete the entry you changed

8. Go back to settings

9. Close the Messenger App on your phone

10. Open the Messenger App on your watch and it should load all messages

This is what worked for me...  I'm not sure how or why, but nothing else worked and I wasn't about to delete anything or reset my phone.  Hope this helps!

I have no idea why, but this really fixed the issue for me. Messenger was spinning for days beforehand. Thanks!

Genius!
