I hit play, changes to playing and then just sits there. Game screen never appears. Just shows Playing now but nothing happens.
Are you using a Razer (Synapse) mouse and/or keyboard ?
If so, see the workarounds described here:
Logitech G604 Mouse and Redragon Keyboard. I have never had an issue playing D3 with this setup till today.
At this point, I would suggest that you contact Blizzard Support with a ticket. You may use this link to start the process: https://us.battle.net/support/en/help/contact/279/ticket
have to play in windowed full screen. Seems I can’t use full screen for some reason but at least AIA can play again.
I never use the full screen exclusive anymore, so now I have something to test for. All of my main Blizzard games I play I run in Windowed Full Screen these days anyway and D4 for example will only allow windowed modes, no longer has an exclusive mode option, since its DX12 based.
