How to set up multiple subnets to see each others?

Hi Guys!

I recently bought a Mikrotik hAP2 and set up everything just fine.
I have multiple bridge, subnets, one for lan and one for wireless.
I can ping every clients connected to both subnet, but i cannot see them in file discovery (on tv and mobile). Is it possible to route them to see each other?

Example: I have a Plex server on 192.168.1.X subnet, but i want to reach from my mobile phone (p20 pro file exploler) - 192.168.2.X. I can reach it from the 192.168.1.X (if i set static for my phone it works too) subnet but can’t on 192.168.2.X

My setup:
