I've had an issue with this before everyone, they are good about fixing it and pretty responsive. From what I've seen, they need to wait on Samsung for this fix.
I'll try to answer everything I can...
I'm running 22.214.171.124 (not even really sure how to update that lol)
Here's the step by step that worked for me yesterday. I did it from the website btw. (Make sure you have room on your Facer watch app. If you have 10 of 10 faces, it probably won't sync a new one)
- Turn on watch, wait for it to boot up fully.
- Launch Samsung app on phone, wait for full boot.
- Find the face you want to sync and put your watch in dim mode. (I dont know why but it seemed to work more reliably when it was in dim mode)
- Roll over the big blue sync to watch button and wait for it to finish fading in. Once the animation is complete, click it.
It should sync at this point. If it doesn't, click it again.
If it still doesn't sync, quit the samsung app on your phone and relaunch it.
Try leaving the app open and up on screen and repeat the process again.
If it still won't sync, quit Facer on your watch and start it again and repeat the process.
If it still won't sync, lol buy a Samsung phone. No, I'm kidding.
Also the issue seems to be just with the iphones.
