Sync does not work between desktop windows and Adroid

I’ve a logseq database sync from my windows desktop machine.
I’ve another logseq database sync from my android tablet.

On my iphone I can sync with the android database, I dont see the desktop logseq database.
Iphone does’t not see desktop logseq database either.

desktop logseq is much bigger than android database, maybe this has something to do with it?
