Premium only subs are blocked from using Devvit apps

Start by reproducing the failure with a premium-only subreddit, a Devvit app using Devvit.addMenuItem, and the developers.reddit.com installation settings. Trace the gateway permission error and the installation-settings error; done means apps can be installed and menu actions can run for premium-only subreddits without either error.

Details

Premium only subs (easiest to create via old reddit) can not use devvit apps.

Repro:

• Create a premium only sub on old.reddit using a normal user account
• Install any app from http://developers.reddit.com|developers.reddit.com that is known to add a sub menu item (eg community-hub app) to the premium only sub.
• Note that a “Something went wrong” message appears when visiting the app’s installation settings for that sub on http://developers.reddit.com|developers.reddit.com
• Note that an error message appears when the sub menu item is triggered. Decoding the error from browser console via base64 reveals a grpc permissions error

Additional info

Discord message: _Hi <@892039441093365801>, I tried installing a Devvit app on a Premium only sub (the kind you can only seem to make via old Reddit) and got an error from your gateway (decoded from base64 and redacted where indicated) when I tried to run a Devvit sub menu item action:

grpc-message:permission denied for subreddit <redacted id>, type: GOLD_ONLY grpc-status:7

Also, the app settings return a "Something went wrong" when I try visiting them on http://developers.reddit.com|developers.reddit.com. I used more than 1 premium only sub to verify its not a sub specific issue.

Suggested repro steps:

• go to old reddit using an non admin test account
• make a new "premium only" sub (or use your admin account to change the type of an existing sub to premium only)
• install to the premium only sub any random app from http://developers.reddit.com|developers.reddit.com that uses Devvit.addMenuItem to add a menu item
• attempt to trigger the menu item
• note error identical to one I have shown (bar text padding) in network tab of browser dev tools
• visit http://developers.reddit.com|developers.reddit.com community specific app page (e.g. https://developers.reddit.com/r/<your-sub>/apps/<name-of-app>) and note the error under installation settings.

I previously tried to reach out via modmail (https://www.reddit.com/message/messages/2gtch6k, https://www.reddit.com/message/messages/2jh2rs7) but the message must have gotten lost somewhere.

Is there any way you could reach out to see if this is an issue that can be fixed?_
