Bugs firmaware Vers. 6.0.926

Hi, My Pocketbook Touch HD 3 has installed the update sw_20200406_U632_6.0.926_user and I am encountering some bugs. Systematically when I resume reading, the reader puts me back 3 pages. has the ignition it goes in horizontal mode and I have to do it 3 or 4 times so that it comes back in vertical mode. It’s a little difficult.
Thank you for help.
