LoRa-E5 Multicast

Hi, I have issues with multicast not working. I work with TTSv3 and multicast messages are sent to gateways, so there shouldn’t be any issue there. Problem is that LoRa-E5 module doesn’t receive them. I’ve turned multicast on on module by following the AT command documentation with AT+LW=MC,ON,018891CF,7FE170FA4F236EE1D7654B319Exxxxxx,3A3F93D72F7E10C721CFB2F207xxxxxx,0 and module replies: +LW: MC, ON, 018891cf, 0. After that I switch class from A to C. Dedicated messages work with class C. Any help would be highly appreciated. I use Mikrotik gateways.
