The “All” selection doesn’t work for deleting multiple events at one time. Nor can I swipe right, nothing happens.
Hey @DennisW. Could you take a screen recording of what you are attempting to do and what’s not working with you? This will help better showcase what concern you are running into. Once you have the recording, you will need to compress it into a ZIP file to attach in your reply here, or upload the MP4 elsewhere and link it here! 
I cannot do that either. There is no all button and delete after you swipe right.
Hi @bplmsprngs. The Ring app has been updated since the posts at the top of this topic were posted. From the History Menu, you can tap the Edit button in the top right corner, then Delete All in the bottom right corner. I hope this helps.
