I was in a similar position as OP and tried switching to other apps (Obsidian etc.), but kept coming back to Logseq. There’s something about the way Logseq’s outliner gels with my brain that I’ve not been able to shake off.
Using Logseq on desktop + Syncthing has been working well for me. Only pain point was Android.
For a few weeks now, I’ve been building a native android app for Logseq (the OG markdown version). It’s finally in a position where I can share it with others. More details here: A fast, native android app for Logseq OG (markdown version)
Give it a try if you were as frustrated with the mobile experience as I was.
