Any chance IGMP snooping is enabled on your system or anything on the network? It takes time for devices to join IGMP groups (on startup or waking from sleep) and it can get compounded by devices using different versions of IGMP.

Did not find any enp2s0 or br0 in boot log, don't know if I need to search somewere else, but i found this setting tha seems to mitigate the "problem": nmcli connection modify br0 bridge.forward-delay 4 (<- secs) now it is indeef faster to catch up , I understand this is a normal behaviour with bridge network and I lowered th value to 4 secs. If anyone has other suggestions, they are welcome.
