There are some feeds which we will limit the amount of data we download from the source. For these sources, if you are a Pro user, you can do a Historic Sync to read all history from your sources.
The process can take minutes or days depending on the source and the amount of data. While this is happening, we recommend that you do not change the settings of this source.
Note Sometimes when you receive the success e-mail, there may still be a couple outstanding tasks while we wrap things up. Don’t worry.
If historic sync is not available as an option for your service, it is because we should have already pulled all of your data already via a regular sync. If you are not seeing it, please feel free to contact us.
