Every time my tablet restarts all the items in my widgets disappear, all I get is "Click to setup or long click to resize". I also get a message saying "Thanks for going pro", but the adverts re-appear as does the go pro link. I have had a pro licence for a long time, I have tried re-installing this but it is still the same. It only started today.
Try unistalling the Kwgt app and reinstalling it.
Thanks, that worked.
