User can't control their device

I had one user that could control some leds, and because I wanted to receive notification if the device turned off I switched the device owner from the user to me and hoped the user could still use the device. The user couldn’t use any mora the device, so when I wstched the device owner back to the user it doesn’t show on the user cellphone blynk app but when I logging to the users account on my computer it shows up fine, we’ve tried logging off and on, uninstalling and instaling back again and nothing seems to work, I would appreciate any help.

What Blynk subscription type do you have?

Pete.
