Hi Alexander.
1)
If you’re making edits to existing events (previously imported to WordPress) and those edits aren’t making it into WordPress, then please do check the box to overwrite existing events: https://cl.ly/0u3y0y1n113B
Please note that any edits you’ve made to these events in wp-admin can be overwritten!
2)
If, instead, your issue is that events from your Google Calendar are not importing at all, could you please try your iCal URL at this iCal file validator?
If you can’t resolve the issue based on that information, please provide me the link to the iCal URL you’re importing, along with any screenshots or links that may be helpful in resolving your issue.
Thank you.
