Ok got it, I've just joined the Beta program and the versions of both apps are more recent than what I installed from the Playstore.To reflect, that app can't cause such issues, it doesn't interact with the system in any such way.
Please check the installation guide. You should join the beta program on both apps in app store as detailed in the installation guide in the first post. That's an old version which doesn't support this phone model
I'll try this and report back if there are any issues, thanks!
