what’s interesting is that if you size your browser window just right, you can actually see that clicking on the menu button does bring up a menu with a single option to download:
i didn’t dig into the code deep enough to determine whether the menu was shifted accidentally or intentionally, but knowing that it’s there, would you rather:
- do nothing,
- try to (un)shift the menu so that it pops up in a typical spot, OR
- remove the menu (thereby removing the download option)?
it looks like Chrome / Chromium adds that download option to its audio control by default. since version 58 of Chrome, the control can be customized via a controlsList property on HTMLMediaElement (see https://developer.mozilla.org/en-US/docs/Web/API/HTMLMediaElement/controlsList). it seems fairly straightforward to remove the download option using this property, but i’m not familiar enough with the Observation page’s code and framework (Bootstrap + jQuery?) to tell you if that would cause any downstream problems.
here’s an example of what the audio control looks like with and without the download option (interactive: https://jumear.github.io/stirfry/iNat_Chrome_audio_control_example.html):
