I have several devices that I use for email, web-browsing etc. recently, I am having a difficult time that is a change from routine, in that when opening emails, windows are very slow to load and just get a round blue circle that goes on for a long time. I have at times turned off device and waited and then reset, as well as checked wifi connection and also resetting the wifi and still this goes on. To me it seems a speed issue. Very frustrating. Ideas?
