LoRa Stack 4.40 and AS923 Dwell Problem

Hi
I updated to LoRa Stack 4.4.0,working with STArm CPU.
i am using multitech AEP MTCDT-H5-210A Firmware 1.4.3
LoRa setup is on AS923 with Both Dwell times OFF.
on the end unit LoRa stack, They have added a check on the RxDone function for a legal max payload received from the server.
Since the default for AS923 is dwell on the commands from the server are
discarded! the unit receives 33 bytes but the max payload is 11.
i think that because the server works with Dwell off it sends long commands after the first message that includes new RF channels and the TX Parameters Setup request (that includes the dwell off set).but the Max pay load query returns max of 11 bytes because the dwell is still on!
I changed the AS923 region AS923_DEFAULT_DOWNLINK_DWELL_TIME to 0
And the problem was solved!. so i don’t know if the server supposed to communicate with the unit as if dwell is on – even if it is configured to dwell off,just because the unit start with dwell on as default, or the end units should not assume that the down link is on upon startup (and let the server set it…)
Thank you
