iPhone 12 and v1.6.0. Update Friday, deleted and reinstalled twice on Sunday.
My share buttons do show up, but they don't do anything.
When you click share -> copy link, the copy link button will highlight briefly then nothing. It doesn't pull up the normal dialog or put something in the clipboard.
When you click share -> qr code, the screen will flip to a blank page and will not show a QR code. This behavior is also present on the web site.
