Refreshing but saving closed tabs?

[lconstable]

Hi josh - thanks for a great utility.

Minor issue here:
Running Big Sur 11.4 on Mac + iOS 14.6 on iPhone, and I'm seeing Cloudytabs refresh with current tabs while saving old tabs that were closed long ago. That list of old tabs keeps growing in Cloudytabs, and I'm not sure why.

Is there a cache to clear, or something else to look at?

Edit: when updating the MacOS, iCloud sometimes gets out of sync. Just sign out of iCloud on your iPhone and then sign back in.
