Google not working in Safari
Ever since we upgraded to Sierra we've been having massive problems with Google on Safari. About half the time searches from the address bar don't work, and if they're not working it's not possible to access any Google sites.
Problem is happening across three different machines (iMac, two MacBook Pros) which made me wonder whether it's got something to do with either our network settings or our ISP, but Chrome seems to work fine, even when Safari won't, so I think it's a fault with Safari.
I've tried switching off search suggestions in the Preferences but that hasn't helped.
It's also transient but frequent (and incredibly annoying).
Any suggestions appreciated!
