MIM-H03N (System AC) smartthings app malfunctions

The system AC has stopped displaying correctly (on the last days) and it is inoperable.
The device is shown on the initial screen and it’s status is displayed correctly. When I tap on it, the screen endlessly loads and the app becomes unresponsive.
I have tried deleting app cache/data and reinstalling the app.
Anyone with the same issue? Is this due to a recent update?
I am on Galaxy 9+ on android 9.
