If I go Settings → Devices & Service → MQTT Devices → Select any device → MQTT Info it pops up de Device’s Debug Info
On the companion App it looks like this:
Full screen, no close button, no scrolling.
If I try to use the swipe back on Android it just goes back on the page underneath.
This remains the same.
The only way to close it is to go to close the App and Re-Open it.
