I'm sorry you're running into these issues with your Google Calendar.
We've had reports from other users as well, and after thorough investigation our development team has decided that the best way to resolve things is to completely revamp our Google Calendar integration.
This is the only way to ensure that the issues will be gone for good!
We expect the update to be released by the end of summer.
We apologize for the inconvenience that this causes! We will make sure to be in touch just as soon as this update is available 🙌
