With a bunch of android apps written using outdated manifest files, an assumed hardware requirement prevents installation on Chromebooks.
This may have been the case with Dynalist, but I can confirm that as of right now, the play store happily installs the app onto my Pixelbook, so I suggest trying again.
However it has highlighted a different problem that I have only seen before on one other android app on the chromebook (although it’s common on my WearOS watch) - it won’t let me install Dynalink using my work G-Suite account because I haven’t set up a lockscreen (which I have, but of course lockscreens are a phone thing, not a chromebook thing).
So I’m going to have to switch my Dynalink to my personal email account to get Dynalink Android to actually start on my Chromebook.
