Hello there, we've been having the same problem with our app since late November. I track the app also through data.ai, that had shown an increase in reviews and the actual review that had been left, then a couple of days later it would disappear and the count would reduce. Now it seems no new reviews are getting posted. We have made huge improvements to our app recently, swapping the platform out and greatly improving our stability but it seems we cannot improve our app score as new reviews aren't getting posted and it's hurting our acquisition efforts. There has to be some way to discuss this with Apple or investigate why this might be happening. Any advice would be greatly appreciated.
