Today I had had "no signal" issue

It happens again and it starts to get very annoying. I have done 12 km and then suddenly had “no signal” issue.

Then I can’t connect my Tacx trainer to the app. So I finish my training with the rouvy app.

And one more, ultimately very often in Android app, screen starts blinking.

It also irks.

Can you tell us a bit about your setup?

Also, have you noticed not everything blinks…
