As a web developer, I only use the app as an XD file viewer. Now, you are pushing me and my partners to continue with a paid plan. But it's not going to happen. You're just losing customers.
Basically, there is no starter plan anymore. It's a trial version. You can not even update the app without subscription. As an Adobe employee, please give us more clear information.
Thank you for your patience, and sorry for the delay in response.
We have an open discussion happening here: https://community.adobe.com/t5/adobe-xd-discussions/adobe-xd-v50-0-12-paid-after-the-update-no-start....
Please let us know if you need further assistance.
We would be happy to help.
