If you want to disconnect a data source, you can do so in your data source settings.
When you hover over the tick of the source you can disconnect it by removing the source.
Please note that all data for that source will be invalidated after removal, it will no longer be updated or shown in any reports. Remember that Compass needs certain sources - Google Analytics and at least one revenue source - to show you valuable data.
After you removed a data source you can simply reconnect the source.
If you reconnect a data source, only the last two years worth of data will be pulled. Please let us know if you need more historical data and we will look into that. Just send us an email to email@example.com.
In any case, please let us know why you feel the need of disconnecting a data source.
