What should be the libhybris version on the XA2? On mine that is 0.0.5.31-1.54.4
According to the Flatpak doc the supported devices should have >= 0.0.5.34

@coderus: Did you get the newer version of libhybris to your XA2 or you tried Flatpak with the same libhybris version that I have got on mine? I am a bit here. Thanks.
