On Screen App Working But Mobile Not Working Properly

Thunkable My project isn’t on Public but here is the LINK. I actually don’t want it on Public - not sure if the LINK will make it Public (it defeats the purpose of paying to have it on Private) but anyway….. The app works perfectly on the laptop screen BUT when played on my mobile iPhone, only ‘some’ of the features work. Songs continue to play when they shouldn’t on mobile. I tried to fix but still, the mobile version is ‘acting up’ and not as responsive as the online version (which works perfectly). ?? How can I solve this as basically, it’s taken me atleast 3 months it seems to complete the app. I’ve finally completed the app and now I have to put it on Public(?) in order to get it solved? This is a ‘mobile version’ isn’t working properly issue. What should I do?
