Exclamation Rev 3.7 firmware update - 09-11-2021, 09:26 AM

I just installed my JB4 last night, when I open the app and hit connect it says the following: Searching for device, connecting to device, validating pin, then it says I have to update the Rev 3.7 firmware. After this I hit update and then it has a pop up saying "DFU starting" and the a loading wheel below it. This is about as far as I've been able to get I've tried multiple times with multiple device and it just spins and spins for even 45+ minutes at a time. Any solutions to this issue? what should i do?
