Very likely it is one of the (usual) issues with PoE standards (or non-standards and the way each manufacturer has implemented or not implemented them).
The CRS328-24P-4S+RM is listed as being 802.3af and at compatible (but also capable of "passive"):
https://help.mikrotik.com/docs/display/ ... yourPoEPSE
While the (oldish) Cisco are definitely "passive" 48 V only, I think there are several Aironet models maybe they exceed the 450 mA limit of the Mikrotik switch, as in theory with poe-out=forced-on and poe-voltage=high they should work, in practice everything (and the contrary of it) is possible.
Did you check the cabling (that the "right pins" are used, didn't you?
https://help.mikrotik.com/docs/display/ ... utpolarity
It could be also a case of a (too) high current needed when the AP boots.
What do you see (if you have it on that switch) with:
/interface ethernet poe monitor [find]
?
