This is relatively new - the past 4-6 weeks. My phone's Gmail and the Google calendar used to synch between desktop computer and phone. Now, increasingly, the two do not synch. The problem is worse with the Google calendar than with Gmail, to the point that I've almost had to stop using the calendar on the phone. Appointments I put into the phone's calendar often never are synch'd to the desktop, or the may appear on the desktop calendar after a few days (not good enough!). Emails which appear on the desktop *usually* do not appear on the phone - ever. It's getting difficult to have confidence in the phone's email or calendar. I'm seriously thinking of changing to another brand of phone. Any suggestions?

(FWIW - Battery is kept fully charged. Removing battery and reinserting doesn't help. OS on the desktop is Win 10, all updates.
