I found a bug on download page (June 3rd 2021)

It's kinda hilarious to see but I think it's too shameful to not be fixed. It says has been downloaded 0 times but it supposed to be hundreds of thousands, right?

Here's the screenshot:

and Here's the link

Hope web developers notice this. Anyway, thanks for making Arduino great :wink:

Maybe just a temporary thing. Here's what it shows for me:

Support the Arduino IDE

Since the release 1.x release in March 2015, the Arduino IDE has been downloaded 52,158,215 times — impressive! Help its development with a donation.

It also might be related to your browser configuration. If I open the page in an "incognito" window, it doesn't show the count at all:

Donate to Arduino

If you like Arduino, show your support with a donation.
Every little matters.

But I'm not able to reproduce your zero count bug.
