Why does the "upgrade to premium" message appear to me if I have a valid desktop license?
If you have a Desktop Premium license, this will not expire. However, as you can see in your license key you have an expiry date for Updates, Support, and Search for images.
If these have already expired, it means that your license will not be compatible with the latest version of the desktop app.
There are two options you can do in this case:
You can extend the Updates & Support from here: https://www.mindomo.com/purchase/desktop.htm?extend
We are currently at version v.9.5.8 and we have made several improvements, changes, and bug fixes ever since the version that you got now.
You can follow all these updates and fixes through our changelog: https://help.mindomo.com/changelog_desktop/
You need to install the version which is compatible with your license before your Updates & Support expired.
If you encounter this situation, please contact us at email@example.com, while mentioning your license information.
