LOL crap my comment never submitted. Thanks Comcast. It was all long and explained a lot. Shame.
I use an iPhone, and all I can say is you have to be aware of what is going on with the software/apps you are running.
Make sure the Download managers you use have an easy locale to your files, in case you need to set up another backup solution. Check off any options that use backup sync, or makes copies of the data on another location on your PC. There was a program that was introduced a while back (I completely forgot the name, it sucked doe) that had the option to backup your files into their selected format, and REPLACE your file with the newer version. The problem was that is was the DEFAULT OPTION. Holy shit did that company go under quick lol.
Basically, you guys need to understand that it is not just APPLE (Amazon and Spotify were just like this too). Anything with direct access to your files (whether synchronized or not), may have a small chance of modifying, corrupting, or even losing them. I've known this since the introduction of these ridiculous things back in 2013. Not just on your PCs, but your phones too.
DRM is a son of a bitch and needs to be put down soon, but that's a story for another day....
Wait until Cloud-Based Services/Storage Solutions become cheap enough, where the average consumer will fall prey to their "terms and conditions", knowing full well that many of us do not even take a 5 second glance at those rules.
