Beatport Link / firmware 1.5.1

Just installed firmware 1.5.1. I got an exclamation mark on the source but it doesn’t explain why. I can see beatport option but it refuses to acknowledge my credentials. I’ve refreshed and checked on other devices with no problems. I’m suspecting the firmware was corrupt and I want to repeat. But how can I do a factory reset and start building the firmware back up from earlier standard. Denon manual has ZERO info on troubleshooting or factory reset. Really quite poor when they’re leading the pack in functionality. Appreciate any help

What bestport link have you subscribed to? Only works with top 3 not the basic cloud option.

It’s one of the higher end subscriptions
