FIX microphone access problem.
Ratings and Reviews
Mic permissions issue .. renders app unusable
I just recently reinstalled this, as it was the best RTA app for my iPad mini. Now I, a paying customer, am getting an error message saying “user has explicitly denied microphone access” or something along those lines. Please let us know how to fix it? Thank you
Microphone no longer accessible
I receive an alert stating that the user has denied access to the microphone. However, the microphone privacy setting within the iPhone settings does not show a request for access. There is no way to allow microphone access if the app no longer request access.
The app performed phenomenally up until this issue appeared.
Is there anyway to resolve this?
I knew something was different.
So my perception in this version, is that it no longer remembers my gain settings and resets them every time... Um, this is no good. Otherwise this has replaced the faulty Andrew Smith app I used for years before they screwed that one up. At least the free version. Cheers
