Yet another note taking recommendation needed

I am currently using Trilium for my notes. But I am constantly annoyed by the mobile experience. What I want:

• sync across devices from a central server (this is why I went with Trilium, as having a web client means there's always the same notes everywhere)
• native Android app with local storage so that I don't have to log in just for looking up a single note (this is what annoys me most about Trilium, plus the UX on mobile)
• web version (for use on PC)

I only need very basic markup, markdown support is enough. I don't worry about security, as I run everything inside my own VPN.

Is there something like this out there? I always see people raving about Obsidian, but sync seems to really suck there. Using some folder sync is a no go for me.
