When transferring files from iPhone to Watch, if you run the app and try to transfer after updating the OS, the transfer may not be possible. (or transmission seems to be too slow)
Just completely close the app, restart it, and try again.
Does anyone know the cause or solution to this problem?
It happened after the last 17.5 update and today after the 17.5.1 update.
The app doesn't crash or anything, and it doesn't happen often, so I didn't send any feedback or anything, but it's strange.
