is wiim app even allow wiim devices on different vlan?

I was doing all sort of firewall rules and tcpdumps
Does the app actually allow user to manage wiim players it finds on different network?
It finds mine but blocks management with "On other networks" with only option to manage is "Forget"

I need to ask why you have the WiiM on another lan than your phone. Is it a Mesh network?

In that case you can change the mode of the Mesh from being a local sub network to just being access points on the main network.

phone in local home network, wiim and everything else leaves in external one that doesn't have access to home. at least that was the idea.

it's different wifi networks on different isolated vlans, home/guest/iot/media whatnot

The split in home and media is a bit unusual and as you state, they are isolated. To allow discovery and communication across those you will have to break the isolation, one way or another.
