May I recommend using any 3rd party app for reddit instead of the official app. I use relay on Android and it is great. There are many other options, all of them are better than the official app.

Use the Apollo app. Much better than the official Reddit app. It's more like what Alien Blue was before Reddit killed that.

Does that make the “open in app” button on the AMP pages work? Because I have the same problem and I’m basically willing to try anything.

Unfortunately no. But there's an "Open in Apollo" option from the share sheet which works for me. It's just an extra tap to open the share sheet from the AMP page.

Also an easy JB for iPhones was posted this week. With that you can make Apollo your default reddit application.

No but it looks at the clipboard when it takes focus and offers to take you to the post.

On Android I have a similar problem; I use Reddit is fun, and so it doesn't open that app; it always wants to download the main app.

It never works for me either, but there is a workaround. If you click on the 'x comments' link at the bottom of a post, it will open up in reddit is fun.

Same here, it always sends me to the App Store. I already have the app installed.

Boost for reddit has been working good for me some quite some time now https://play.google.com/store/apps/details?id=com.rubenmayay...

Make sure to try i.reddit.com in a browser, that's also a good option.

You should really try Apollo.
