Apple Watch SE

You guys really need to advertise more that this lets you upload MP3 files from your phone to your Apple Watch and let’s you listen to them offline for free and without ads!! This is the best offline media player app for Apple watchOS by far!!!! You guys would get a lot more downloads and 5 star reviews if you drew in the right traffic, this app is amazing!!!

Deleted a copied folder and it deleted the original and the files are not in the trash

I was hoping to use this app to help my quickly transfer files from my SD cards (I work in video production) to a hard drive while I travel. I attempted to copy a folder from the SD card to my hard drive. However, the files didn’t fully transfer from the folder. So I figured I’d delete the copied folder and tried again. Doing so for some reason deleted the original folder as well. And when I went to the trash bin in both the app and my iPad’s trash bin, the files could not be found. Thankfully I was just testing the app and the deleted files were just some personal photos from a trip. But I would be livid if it were my client work. I wouldn’t trust this app with any professional work.

Can’t upload many files at once

The IOS Files app can longer works with Google Drive as it results in an “authentication needed” error.

I finally found and app that can connect Google Drive to the USB portable drive connected to my iPad. It won’t let me upload directories, but I was able to hit “select all” and start uploading files. The problem is that it uploads 5-7 files then just stops. No explanation. Waited for a half hour, nothing further has happened. Eventually, I got pop up that said the files that I was trying to move over don’t exist. Went through this process several times and gave up.
