Pro Trailer Hitch not working after adding 21 IPMA for APA

[asouza68]

Anyone else's Pro Trailer Hitch not working after either an OTA update, or after putting a '21 IPMA into a my23 to activate Active Park Assist? It won't or allow Pro Trailer Backup Assistant. I notice the headings are grayed out while it's trying to initialize. It tries for a while then times out. I haven't tried it until today. It was working before I added the '21 IPMA, but don't know if that's the reason. @Jesse-Infotainment has been helping me trouble shoot it, but wondering if anyone else has experienced it?

Best guess would be you need updated software on the module, but if anyone can figure it out, it's Jesse
