Connecting Leviton Smart Dimmers DZMX1 to Home Pro

After attempting to install my 16 Leviton controlled lights that could not be migrated from Homey Cloud to Homey Pro 2026, only 4 of the 16 would install. Can anyone point me to a solution?

Is there any error message displayed? Or is it simply not found?

No error message. When on iphone app once you get to where it should connect (sometimes does) after the amber light and green light, the app just does not connect. No message. Thanks
