The app is not stable right now so all we can do is wait until it gets fixed. But I believe the review did get posted, just that it's not loading. I tried posting reviews and they did eventually get posted eventhough it seems like it didn't. I ended up having multiple copies of the same review because I tried posting many times. Had to delete the multiplied ones. I also did not receive any points for my reviews...so yeah, lots of glitches 🙃
