UPDATE: Issue resolved in v5.49
Incoming call problem in watchface mode
I have just received the MM update on my Huawei watch, and noticed it. I already have an idea for a workaround, which I will include in the next update (not in v5.4x that’s in beta, but after that).
Until the update comes you can tap the clock bubble to reveal the phone app. This works for every other case when the watch-face covers an app (as shown in the short video below)
Thank you for your patience!
