it seems like it's working i just start uploading a file, and it uploads, then the snap image does too and i go to publish and it says (you need to upload a vid first) but i did and it loaded and everything but it wont submit. i tried a few times and logging out and back in but nah

Try once while leaving the dtube upload page open on the screen during the upload, and then don't use the computer for anything else until you have posted the video. Ugh this is the major problem with steemit at this point, and that is the dapps running on the steemit blockchain are all a bit clunky.
