other8026 you'd have to test on a device with the stock OS to find out for sure
Unfortunately I don't have a stock OS phone to test out the app with. Having said that, I do feel inclined towards the possibility of Instagram discriminating against alternative OSes by blocking this feature on certain places in the app, but not for the people I know.
I should also add that I'm unable to use "Join channel" buttons in stories, and I can't share channel messages on stories. Again, it appears to be a non-issue for general users.
But before jumping to any conclusions I do want feedback from other GOS users if they can replicate this issue.
And if it is indeed a pushback against GOS or custom OSes, then it might be prudent to uncover what exactly the app detects to implement this block on such devices. In fact my concern with allowing to work around FLAG_SECURE is apps then going out of their way to block them from running on GrapheneOS completely.
But as usual, I trust the devs will make the best decision for us users 🙂
