I have to correct myself. Krisnan is right, it functions awhile after reinstalling, until to the point where during reading the white bar drops down and BEHIND the 'coinmeter' in the right top corner, there is a button 'details' which I simple cannot click due it's location, if it were in the middle no problem, but not behind the 'coinmeter'.
After this I cannot read anymore.
My settings, 'Night Mode', 'Disable Page Turning by volume Keys', 'Smallest Font', 'Rubrik Font', 'Scroll Up/Down'
I tried it again with reinstalling anew and then using as well the mini update, still the same error, though there was no bar going down with details, just freezing and then back to library.
