Purchased, now says I have to repurchase?

I purchased Goodtask for both Mac and IOS in February, including Pro update. Just now received a message saying I had 4 days on my trial ... What happened and how can I fix it? Can't seem to bring up message again ... I kept receipts if needed ...

Hi @BradPuett, thanks for using GoodTask.

Normally it shouldn't work that way. If you have trial version on your Mac, remove that and make sure you're not running it.

You may send me screenshots to contact@hahaint.com if the issue persists.

Thanks!
