HI @Stephanie_Oberg and apologies for the delay in responding.
These updates are pushed directly by Google, technically they should happen at least every 24h, but we have no control over it! If you continue running into trouble I’d recommend disconnecting your calendar and project and try to sync them again to see if that helps.
We haven’t received any other reports, so I don’t believe this is a wide spread issue, but if the above doesn’t help, please report the issue to our support team with some screenshots so our team can investigate this further.
