TCU Onboard embedded modem firmware update 1.4.4

I have been having problems with MFM losing communication. MFM phone support said I needed the firmware to the modem updated to 1.4.4 and only the dealer could perform this. Took about an hour. I get home and still not working. Dealer says bring it in next week. MFM phone support says it is still 1.4.3. Dealer has it for two days and tries to say my iPhone software is not up to date. MFM support says the dealer is not a recognized EV dealer and to go elsewhere. I drive 25 miles to a dealer who “has an idea” of what needs to be done. An hour later they have no clue. Anyone experiencing this? Almost at the end of my warranty and getting worried what incompetent dealers may charge for software updates that take days to figure out.
