Same problem here.
The upsetting part is that I paid quite a bit to use their apps across all of my platforms already and now what I paid for is gone. How is that okay with Apple's App Store?
If they wanted to go to a subscription method, fine, but do not delete the apps I paid for in full. Other developers have just created a new version of their app and left their old paid apps as "Classic" and left them unsupported (i.e. I use AltaMail and this is what they did and am fine with it).
Try reinstalling app on phone again and reboot both devices. Watch app is working for me on s5.
You agreed to the trial, correct? I wonder how that works as a paid user. Does that force you into the free zone that somebody who downloads it for the first time and subscribes for a trial would be in?
What happens when the trial ends? Do we keep our features we paid for?
