If your Readwise account has a large amount of data (over 5,000 highlights), you may see this screen when connecting it to Heptabase. This happens because syncing a large dataset can cause performance and stability issues.
If you'd like to connect anyway, please contact our support team. We'll review your case and can enable a bypass for your account. Once it's enabled, restart Heptabase and try connecting Readwise again. Keep in mind that with a very large library, some parts of the app may feel slower after the import.
