My HTC One M8 updated to Marshmallow, and now my call history shows blank. Using the file explorer I can see the recordings are there, but Call Recorder has not re-indexed after the update.
Reading the forums here I see that there is currently no way to force the app to re-index. This is a significant loss of functionality, since it effectively means updating to Marshmallow breaks one of the most important features of the app, which is to play back recorded messages.
Is there a fix?
