Since you are with AA, there isn't a full OTA for AA yet. Only an incremental OTA is available for now. Since you are rooted incremental cannot install. Only way would be to uninstall magisk, update incremental. Get the boot.img once incremented, patch it and install it thru fastboot.I'll just leave the root and bootloader unlocked, I don't want phone to be wiped if I lock it back up. I do get a firmware update to 184.108.40.206 but it wont download and keep giving me error, had a quick check online and the OTA for that global version isnt out yet. I think the HOS cust.img is 220.127.116.11 so maybe that's why it's telling me there's an update?
