ADDENDUM:
After I first installed the 2.6 version on one of the Android phones (both Oppo with ColorOS), I was able to update the firmware of the S30 and have it restarted, but then the 2.6 version app has completely stopped working, crashing on start, even after having restarted the phone. Finally, since I also have an IPhone XR where I never before installed the Seestar app, I tried to install it there, but here too the 2.6 version app crashes on start ... this is really absurd. There could be something wrong with your app images on the stores, but all my problems tonight started with the 2.5 version that worked perfectly (on both scopes) the last time I used it.
