Just got a new TV (Polaroid 4K 50') and I can't download any new apps or update the existing ones. Whenever I try it just says "pending" indefinitely. I've searched online for solutions, most of which say to delete the cache from Google play/play services/download manager or uninstall the updates, neither of which have worked. The TV is brand new and has plenty of storage space, any ideas on how to fix this?
EDIT: The issue with solved when I added my other Google account to the tv.
Had this happen with a couple of other devices. I deleted the Google account. Then reboot, then add Google account again and it works. Hope this is good for you
