As a Roblox developer, it is currently too hard to share deeplinking URLs in experiences, currently, we have to show the entire URL to a player then have them copy it into their clipboard.
This is difficult to do on Mobile, where it would be more effective to show a QR code containing the deeplinking URL, however, the issue here is that QR codes are basically not allowed anywhere.
Instead, QR codes should follow the external link policy that is used elsewhere on the website, not to mention QR codes that dont even contain URLs.
If Roblox is able to address this issue, it would improve my development experience because it would be much easier to share deeplinking URLs within experiences, especially on mobile.
