### 1/5 — Couldn’t integrate

*2023-10-12*

I had to delete this app after multiple attempts to get my watch to recognize it. Phone iOS is up-to-date and I am using watch 3 with up-to-date software. The app didn’t show up in my workout app, or even as an app to open but simply didn’t appear anywhere. I rebooted both my phone and my watch and nothing.

**Developer response:** I'm sorry that you had issues, we will take a look and try to solve the issue as soon as possible. Sorry for the trouble
