Great app
You can quickly download and upload send links using Email and WhatsApp. I got tier 3. The user interface is very simple, and I am still getting used to it. Here’s what I like:

1-Fast
2-You can upload multiple MP4 files and send a single link via Email or WhatsApp. All videos will be in one collection, and the receiver can watch them one by one without downloading.
3-You can set an expiration time for the link, and if you want to use the file again, you can set another date.
