protonc,
TY4 the reply.
All browsers are closed during play, with only the game pop-up opened. Reopen browser on WGT page from History only for return to the game in-play then closed.
Memory & CPU speed are not an issue as this is the max build Surface device. WGT is the only app/tab in which the shutdown occurs.
I posted for discussion as most of my opponents in the Showdowns face this issue as well.
The WGT Team responds to any issue reported, but is unable to determine the cause during the past few weeks.
Since Day #1 almost ten years ago, I've played on Surface Tablets only and have reached Tour Champion status.
History, cache & cookies are cleared as daily maintenance.
Add to the mysteries of life. Haha
Keep pushing your rock up the hill, mate.
Cheers,
