@SouthSeattleNeighbor Are you able to convert the .mov file into a .mp4 file? I can confirm for you that we 100% support MP4 files, but MOV files can be a bit iffy on if they will upload, especially if it is a UHD MOV file. Converting this over to MP4 should help eliminate that concern. When it comes to max file size, we support up to 200 MB, so you are good on that front.
In addition, if the video fails to upload, try uploading it and accessing it while on mobile data only if you were on wifi, or on wifi only if you were using mobile data before. Let me know how this goes!
