Insync app not recognizing my purchase online

I have installed Insync on my Zorin OS laptop and synced my Microsoft Online account. However, I plan to shift everything towards Google Drive.
When I purchased online, after installation, I chose to login with my google drive email. I use the same email for both Microsoft Onedrive and Google drive.

The app on my desktop still says 7 day free trial, not recognizing my purchase.

Please help!!
