Hi I am new to this site. I am also new to posting threads. But just retired, got new tablet a couple of months ago and just got new computer. I will get on top of this, at least enough for my satisfaction!! So I just got my computer a couple of weeks ago and have been neglecting my tablet so not real sure when this problem started with it (the tablet). Having problems with security: "There are problems with the security certificate for this site". "The site's security certificate is not trusted..." Have tried going to settings and unconnecting to my Wi-Fi and starting over. Have tried going to my gmail, going to Force Stop and Clear data. These did not work. What other suggestions are there? Everything is fine on my computer. Thank you so much.
