@UdokaObis how long was the video you’re trying to upload, and what’s the image size? It might be good to try uploading a shorter video with smaller file size and see if it goes through.
As for reduced points and reviews removed, make sure your contributions didn’t violate the rules. You can check the article below for prohibited and restricted content on Maps. If you find any violating items, you should edit the contributions accordingly
@UdokaObis how many videos are you trying to upload at one time? Try uploading one video at a time. Also if possible try uploading the video through Google Maps on a computer, see if it makes any difference.
