I keep getting flyout messages from Windows 10 regarding my Verizon Yahoo and Gmail accounts are out of date and need updating. When Microsoft first installed Windows 10 on my computer everything worked fine and my email accounts synched OK after I inserted the passwords. I use Firefox as my browser, instead of Edge most of the time. Both of my email accounts work great on Firefox and my Android HTC One. Question, how can I stop the flyout message from the Activity Center? They are a nuisance.
