Markdown not rendering

Hello everyone,

I'm not sure if this is a known issue, but I haven't found a GitHub issue about it.

Markdown doesn't seem to be rendered (correctly) in the app in some places. For example, spoilers don't seem to work, nor does strike-through text.

:::spoiler Test Spoiler This is a spoiler text :::

This is a crossed out text

There seems to be no Markdown rendered at all in the summary card of a post.

This is a bit of a problem for me because I want to run a community for a book series and I want to hide spoilers, especially in the overview, so that new readers don't miss out on the fun.

If this is not already known, I will be happy to create an issue about it.
