UPDATE: If I have to use a browser to transfer my other files, I'll just use the browser to transfer pictures as well. I say again, not much use for this app. OLD REVIEW: It only allows you to move pictures and videos. Some people use other file types like DOC, PDF, XLS, etc ... This app won't allow that. You'll have to use a browser if you'd like to move non media files around. And if you have to use a browser then there's not much use for this app.

Hello, Thank you for your feedback! Our app is currently optimized for photos and videos to ensure a smooth experience. We understand the need for other file types like DOCs or PDFs and are considering this for future updates. For now, the browser option is available for those needs. We value your input and are committed to improving!

I would give this less stars than 1 if possible. the app is now completely unusable. it keeps asking for a code then doesn't use it. I ended up having to log into my email on a PC (something I haven't done in 5 years) because everytime I left the app to get the code it generated a new code. nicely designed!

Love it on my smart tv. It's flawless. However, on my android smartphone, it's horrible. When I play music from the mycloud device to the phone and connected Bluetooth headset, it plays 1/2 to 3/4 of the song and then starts over again. I've tried everything I can think of but can't make it work. Network is fiber and 100mb.
