To be honest, I thought things had improved with connectivity, but since the update to the blinding flash (and the subsequent reverting back) issues have increased again.
Maybe some issues have decreased because players themselves close the browser after 9 holes and clear caches etc. but I have had several alt games not finish and even stroke play rounds not finish (this one is odd, a 3 discons will DQ a player in the past, but now it does not let either player finish?)
Personally I now expect an alt game not to finish, so prefer not to even bother. The number of m/p games that finish in the same way.......simply means I will play less until it improves again.
