Do you have a link to AzDO for any of the failed run? As stated in #74225 (comment) the conditions should already prevent it from running on Android so this looks like some weird mix-up.

[rzikm]

Sorry, should have included a link in the post, edited

I see, I have accidentally commented a part of the query I use which excludes runs from "runtime-staging"... not sure what that is but the failures don't show on checklist on PRs either, so probably false alarm.
