First of all, you need to confirm which app you purchased, the Dev Tools App or the Dev Tools Pro App? They are two separate apps.
If the purchased item is "Pro Version-Lifetime (Dev Tools(Android Developer))", it means that you have purchased the Dev Tools App; If the purchased item is "Dev Tools Pro (Developer Tools)", it means that you have purchased the Dev Tools Pro App.
If you purchased through Google Play, please:
a. Install "Google Play" App and open it,
b. Login to "Google Play" with the google account you used to purchase Dev Tools or Dev Tools Pro,
c. Click the "Account" menu in the sidebar and click the "Purchase history" submenu to ensure that you can see the previous purchase history,

It should be able to be used normally. If it still doesn't work, please feel free to contact me by codekk.com@gmail.com

5. The Layout Inspector is sometimes inaccurate
If you access an app A from the recent visit list, the layout viewed by the Dev Tool's Layout Inspector may still be the layout of the previous app B. There is no particularly good solution to avoid this. You can click the desktop icon of the app A on the desktop again, and then use the Layout Inspector of the Dev Tools to view it.
