Can't upload a video.
If I tap "Create", then select an MP4 of about 22MB it says:
Size of image number 1 in the album exceeds the maximum size allowed by the instance (22938 kB but the limit is 40000kB). You might not be able to upload it.
But clearly it is smaller than 40MB. I click OK, then Next Step, then it says:
One or more videos are still encoding. Wait for them to finish before uploading.
But, they never appear to complete.
