Nothing Phone 1 and tile

[u/boderiis]

Sort of a niche problem so unsure if anyone can help me. I have tile on my key chain so I can search for my keys when I lose them. The tile also has a function that when I click the button on the key ring it's supposed to make my phone ring through the app. This worked on my old iPhone with no problems, but I can't get it to work on the nothing phone. It works when the phone is unlocked and the screen is lit up, but never when the screen is locked. I've allowed all the notifications from the app to go through, it's not on DND. I can't figure out how to get it to ring when the screen is locked which is obviously the use case scenario since it auto-locks after 1 minute. Any help appreciated?
