Figma Mirror doesn't display different artboard in the same page

Figma Mirror on the iOS app no longer updates in real time when I tap on a frame in the browser or desktop app.
I can load a different artboard if I switch to a different file, but within the same file, Figma Mirror gets stuck on the first artboard I select. Before starting Mirror, I can see the artboard name update on the iOS app when I switch between artboards. However, once I start Mirror, it stops updating.
