Hi @q199493422. I didn’t have any problem downloading it on Windows. I’ll have someone try on Linux to see if we can reproduce it.

Sorry for the delay on this. We’ve confirmed the issue and log an internal ticket for it: OM-72657. Thanks for reporting!

The devs tell me this is fixed now. Please try the extension again. :)
