Just in case anyone finds this in the future, Mikrotik support managed to solve this for me by setting the following modem-init commands. Just replace <YOUR APN> with the APN of your provider.
Code:
/interface lte set lte1 modem-init="AT+CGDCONT=0,\"IPV4V6\",\"<YOUR APN>\";AT+CGDCONT=1,\"IPV4V6\",\"<YOUR APN>\""
