So, you have logged in to your Tickera account and navigated to the Licenses area where all of your Tickera licenses are listed but when you clicked the particular license, you have noticed that there is no option to renew it. This simply means that your license is still not due for renewal. You will receive an email 30 days before your license expires which will contain a direct link for license renewal. And, you will receive similar reminder emails 7 days, 2 days and one day before your license expires (if you don't renew it at some point, of course).
If you encounter any issues during license renewal, please send us an email here.
