I am setting up a new computer, so wanted to have Purple Air bookmarked on it, of course. Brought up the map, and ALL of the dots/sensors show up as gray with no numbers or colors unless I click on them individually. When I click on them it says no activity in the last 15 hours (something like that) in the box that pops up, but dots are still gray, but meanwhile on my iphone or another computer, they are showing colors and numbers at the same time I am getting gray on the new computer. I matched options of the other devices, with no difference. Anything the new computer might be missing that would do this? Or any ideas? Thank you.

Does the behavior remain when using a different browser on the new computer?
If so, this issue can be caused by having the wrong timezone set up for your operating system. You’ll especially want to double-check this since you’re setting up a new computer.

I finally figured it out. The computer came with a weird default of some arbitrary date and time, so Purple Air was looking for input in the last 10 minutes but the computer clock said it was a different day and different time. I changed it to auto clock timing, which brought it to the correct time and now purple air works. I have not come across that situation before, but all is well now.
