What issue do you have?

I have very different sync speeds on Android. Is that normal?

On mobile network:

First sync after launching the app: > 30 seconds (without any changed notes).
Deleting a note: <2-3 seconds
Manual syncing: > 30 seconds
Creating a new note: > 30 seconds

On wifi

First sync after launching: > 30 seconds
Manual syncing < 2 seconds
Creating a new note: < 2 seconds
After display-timeout: > 30 seconds

On openSUSE Tumbleweed (on wifi or mobile network) all synchronization is very fast.

I run a Joplin-Server (3.3.13) in a docker on a Raspberry Pi 4.

I initially thought it might be due to my network setup, but it's much faster on my laptop with the same setup.

Are you using Tailscale by any chance? If yes, try seeing if a continuous ping from your rpi4 to your client devices helps. Worked for me.

No, I don't use any VPN. I use DynDNS from my router (myFritz.net).
