When I had an online mode, for example I read 50 pages and stopped at the 100th. I stopped reading the book. Clicked "close", went to the general menu. Enabled offline mode. I read another 15 pages, that is, at the moment was on the 115th. Pressed again to "close", went to the general menu. Again I switched on the online mode and again started reading the book. But the book opened on the 100th, although it should be on the 115th, because I later read locally
