Adobe has been a disaster for years. Their answer for why files don't save on network drives properly is "because that's unsupported".
They were also the WORST company I've ever dealt with as a vendor, and had the biggest raging *******s in charge I've ever seen. That's not an understatement.
My typical answer when a Marketing person comes to my desk and says they're having trouble with something made by Adobe is a smile and an, "Of course you are."
They are an unacceptable product and an unacceptable company to deal with. Those of us who know this, simply put up with the world's addiction to them and their overpriced proprietary garbage.
We refuse to officially support their crap in our environment. We've made it clear that they're at best, a difficult vendor and at worst, actively ignorant of how to do customer support on their products, and all support is done on an "best effort" basis.
Marketing still loves the crap. They live in constant fear of it breaking and us saying, "Enjoy keeping both pieces when it does." And yet make no effort to learn or use anything else.
It'll be their deadline that an update of the "subscription model" software they've chosen to use, keeps them from meeting, someday. We've washed our hands of it. There's not enough time left on the planet with me breathing, to deal with Adobe and their crap. I can offer you an 800 number if you'd like to see what they'll do for you in person, and see why we do not support their products anymore. Enjoy.
