LAG not all interfaces work

Greetings

I have the following problem

I have three wireless links
at each end I have swos and I use lag to be able to add the links

the problem is that only one interface receives and transmits and the other two only transmits

I attach an image of the LAG configuration and the network diagram between my provider and my Core, which is a CCR2116

Thank you so much

Likely working as designed, see https://help.mikrotik.com/docs/display/ROS/Layer2+misconfiguration#Layer2misconfiguration-Problem.2. You cannot change the transmit hash policy in SwOS, from the manual CSS610 “load balancing based only on Layer2 hashing” and CRS318 “load balancing based on Layer2, Layer3 and Layer4”.

What could be the implementation that I would be needing so that I could do the job correctly?

Replacing the CSS device with one which supports other hashing methods may help - it depends on the source and destination MAC, IP, TCP/UDP ports of the traffic in question, and how they vary for the traffic streams.
