This is a big part of why I dislike platforms that consolidate downloading and viewing.
I’ve been using PerfectViewer on a tablet for viewing for ages. There exist any number of ways to download and sync the chapters. I currently mostly use the mangadex-dl script and a syncthings folder and it’s no trouble. And all my read chapters I can just move into an archive drive where I’ll have them if anything ever happens.
