I am nowhere near the servers, the mods are all volunteers. I have seen some issues posted concerning problems since the Windows 10 April update (as Microsoft has been calling the update), but no particular answers yet.
Do you know what I noticed?
When I click on the "Select sync data" button, the screen blinks as if it wants to open a tab. https://ibb.co/dtvRKS
Maybe it's this?
I allowed tabs to open, but that did not help.
