/showcommands prompts a Lua error on iOS, tested on both my iPad and iPhone. Lua error is posted below. Apologies for the text-for-ants. If there is a way to make the Lua error text a big easier to read, let me know.

I don't think /showcommands has been propagated to iOS yet.

Basically, every time we update on iOS, Apple tends to give us a hard time about some random new thing they decided they don't like. It's unpredictable (not based on stated policies) and very time consuming, and it causes us to not update the iOS binary very often. Most updates don't require a binary change.

I agree though, the tiny text is a bit silly, we'll see what we can do about both of these issues.

I see, that makes sense as to why it's not functioning. It's calling for it, but has no end-response. Thanks!
