So...My workaround. After 3 months of deleting, resetting, clearing, calling tech support, and close to tossing my S5 off the bank, I found the way around my PLAYSTORE errors and inability to download was simple really. I downloaded FireFox. Yes using FireFox instead of Chrome did it for me. So let me be clear, this did not fix the issue of tapping the PlayStore icon on the phone, but works if I launch FireFox then navigate to the PlayStore. On my tower and phone I was using Chrome, on the computer I would get the message that this content was not available in my country, and on my phone it was an error retrieving data from server. When switching to Firefox, Play Store opens and I can choose and download apps to my phone from my tower, and on the phone using FireFox the Play Store works as it should. Hmm? I don't code but this is a strange issue, and the above option worked for me, now I can actually call Uber when needed or stranded with a flat tire. Best to you.
