Speak to Formuler Devs. I've said it a thousand times.
For information to outsiders, formuler boxes have their own bespoke software and it's the only one so far that has issues, not sure why as I don't have one.
It's not a priority for me as mag devices are a load of shit and should be binned, but speaking to formuler and explaining the issue may help as they have access to the software to resolve the issue.
My MAG API isn't automatically compatible with everything as I've had to make sacrifices and changes to support security and speed enhancements, if that breaks one or two devices who cares.
