How can I easily and conveniently transfer files wirelessly between my linux computer and android phone?

I'm running OpenSUSE leap 15.5, When I was on the linux mint, I was using warpinator but using it on openSUSE is troublesome and I wish there was a linux version of blip but unfortunately there is not.

Syncthing
Never could get it to work with phones, and that from Arch, Mint, Asahi, Macos all sharing flawlessly between thembut no phone would reliably stay sync’ed.
What phone are you using? I’ve used it my many Android devices from various manufacturers. Always worked flawlessly.
I have a 2-year old android 11 oppo A53, my colleague some small samsung on A10. Installs fine, sync a first time somewhat, then just don’t sync a thing.
That could be a permissions issue that doesn't allow the app to run on background, Maybelline?
Something like this happened on my sister’s laptop. She got a new laptop with windows. She followed some website to set up Syncthing, but it wasn’t syncing. Turns out, there’s some kind of “trusted network” deal that needs to be figured out. (Don’t remember the exact term anymore.) Anyway, helped her fix it, and installed Debian Stable on it the next time I was visiting.
