Edpuzzle...Grrrrr....

I love the idea of Edpuzzle, but it always seems to have some glitch or other, and my best students can't stand using it. My kids have ipads, and have to download the app to complete the assignments. Then, it it difficult to time the questions so that it comes right after the material that answers it. Then there are the odd things that happen: Today, it decided to post three of the same video for students to answer (maybe because I edited the assignment after it was given).

So, is there another site or app which does the same function (videos with questions), or have people figured out how to make it work consistently?
