A Wear OS update a few days ago messed up Facer on my Galaxy Watch 4. Facer is now running again on the watch using a randomly chosen Facer face but I have not been able to upload any of my own faces from the Watchbox of the Facer app on my Android phone.
Every time I trry to do that, I get a message on the phone to say that “Facer needs to be installed on your watch”. What am I doing wrong?
I get a similar problem when opening the Facer App on my phone, going to Watchbox and there’s nothing in My Designs anymore, Collection. My Designs actually shows a message saying that “You haven’t designed any watch faces yet” which is extremely odd 
I have the Galaxy Watch 4 Classic and Galaxy S24 FE phone.
Edit: Sorry everyone, mistake on my part! 
I updated the App and forgot that I needed to sign back in…it’s all perfectly fine for me now 
I just checked on my mobile - watchbox and downloading to watch is no problem
Instead of using the Facer app on my phone, I opened the web-based Facer design page and tried to transfer one of my faces to the watch. I then saw the message “Syncing to your watch… (non-Wear OS6)”.
Do I have to modify my face designs in some way to make them compatible with Wear OS 6?
It’s likely that you will have to do this.
