If anyone with #accessibility knowledge and a few minutes to spare would be willing to watch this short video (1 minute, 28 seconds) and let me know about any #a11y issues you notice, I'd be grateful.

It's me navigating through an iOS app with VoiceOver, using a double tap to open the "Slider menu alarm icon, button", then a single finger flick to the right to navigate through everything else.

Thank you 🙏

For the avoidance of doubt, I have a fairly good idea what the answer is, but I'm hoping for independent corroboration 🙏
@tink In the expanded menu, there's a number of decorative images not hidden from assistive technology, and towards the end of the menu items, a horizontal separator line receives screen reader focus. Focus not trapped in the menu. In the main area, after the range, there's a mislabelled image of an arrow that's horizontal and points to the right side of the screen, possibly to communicate the trend of the current reading (?) and then there's an unlabelled button, its visual label is "Add note".

@tink Observations:
• No announcement that the slider menu has opened.
• Menu is not immediately after its trigger.
• Menu options are not announced as menu options (making “slider menu button” a lie).
• Many images in the fake menu have no alt.
• “Reports” fake heading in menu is indistinguishable from other options.
• Images not excluded from navigation.
• Menu thing does not close when focus leaves, obscuring focused content behind it.
• An unlabeled button at the bottom of the screen.

@tink
In short, this seems like a broken menu or navigation thing with a handful of obvious WCAG failures.
