I don't think anybody has a fix, especially because nobody has your phone at hand to find the problem, this is just wild guessing what could possibly be wrong.

One other thing that comes to my mind is that there might be another app that is interfering, especially since you said it was working for the first weeks. Try to uninstall any other apps and see if it fixes the problem. If it does you can install one after another again to find the responsible app.
