I purchased a license to TaskPaper 3 in Nov of 2015, but recently I’ve noticed that I must re-enter my license information each time I open the app. I just tried this with versions 3.6, 3.6.2, and the 3.7 preview, all with the same result. The issue occurred on Mac OS 10.11.6 and 10.12.3.
Any help would be appreciated. Please let me know if you need any additional information.
