I have a license.
Need to use it on React.
Where should I put my key?
You need to activate the React package in the customer area (https://www.daypilot.org/customers/). You'll be able to get a npm installation link there as well.
I went there.
Package installation links:
No releases available
Is it because my license expired on nov 27th?
If it says "No releases available" it means no releases were found for your license. This can happen if your maintenance subscription had expired before the first React package was released ( June 1, 2018). In that case you'll need to renew the subscription to get access to the latest release.
