Thanks for the comment!
I don't know how long you've been uploading, but things were even more shaky when I started in December. I sometimes had to keep trying for multiple hours on 4 seperate browsers.
The only advice I can give you is try using "handbrake" to compress your videos and try uploading vids less than 10 minutes for now.
I dunno how powerful a tablet/laptop is but a dedicated laptop is definitely better for editing
I'll try handbrake. I use a computer to edit and then transfer the finished video to the tablet to upload. Sorry to offload all my frustration on your post!
It's fine, Vent away!
