I have a Gear S3 frontier, this was working ok with my iphone 7, but then i got a new phone, an iphone 8 on IOS 12.3, since then the samsung galaxy watch app will not accept my username and password. I can sign in online with the same credentials, I have tried deleting the app and reinstalling. Samsung customer help were terrible, first telling me that you cant use a samsung watch with an iphone..., and then eventually telling me that the problem was with the app developer and not samsung (the dev. IS SAMSUNG!!) The watch is rendered useless, I cannot put the apps that i need back on as i had to reset the watch to pair with new phone.
If there is a fix for this then please let me know!!
