Do you cache content/data?

Yes, we do have a caching mechanism to speed up the page rendering. The data from Google Sheets is cached for 1 - 15 minutes and after this time, the data gets pulled again from Google Sheets again. However, if you want to pull the latest Google Sheet changes immediately for testing, you can always open the project and click on Data Sync option at the top right corner.
If you want to disable cache and want to pull data from Google Sheets everytime, please contact-us and we will be happy to work with you.
However, for Supabase data source, we don't cache the content and we always pull from live source as Supabase supports high volume reads.
