Add/Update buttons for calendar sidebar not visible in Android Chrome Browser

With Chrome on Android, using a Nexus 5X and a Galaxy Tab S, nextcloud 15.0.8:

When I add a calendar event, a small pop-up opens. To add attendees I click on “more”. The sidebar for the calendar event opens on the right-hand side. I can add attendees but the blue “add/update” button is outside the visible area and it is not possible to scroll to it.

For existing events I can also access “remove”, “cancel” and “export”.

Works on Windows Chrome.

Anyone else seeing this?

Attached a screenshot that shows the android button bar at the bottom hiding the calendar buttons. Scrolling only scrolls the content above export etc.

Apparently a known bug:
