Day view not clickable on opening app

On opening the app, I am presented with the current Week view, but the Day tab is highlighted at the bottom. When I click the Day tab, it doesn’t switch to this as the tab control thinks it’s already selected. In order to view the Day view, I first have to click on Week/Month/Year, and then select Day. iPhone 13 running iOS 16.5.1, latest version of the app as of 15/08/23
