I just downloaded ArcGIS Survey123 Connect (3.12.232) to create a new survey to publish to AGOL. I installed the application and upon opening the application it is painfully sluggish. Hovering over the three ellipses for each survey, the pop-up will fade-in in steps over about 4-5 seconds. Hovering over the existing published surveys the image will zoom in/out extremely slow (2-3) seconds in steps. Opening a small survey will take 2-3 minutes.
Never had this issue with other versions. I tried re-downloading the app and reinstalling with the same results. Also tried installing as Administrator and tried both the 32 and 64 bit versions. Additionally, uninstall does not work from Windows Control Panel.
I also tried to create a new blank survey with the same results.
Running on Windows 10, 64 Bit OS.
