I just bought the Vivoactive 4.
I have followed the instructions on this page https://support.garmin.com/en-GB/?faq=38806ssQXt5U9FObj1hTPA to setup Amazon music.
When loading Amazon Music on the watch (step 2.4 in the link) i get the following error:
"Cannot sign in. Try again later. (-300)"
Does anyone know how this can be resolved?
One of the key reasons for buying the watch was to be able to listen to music.
Thanks a lot.
