Canvas: Is there a way to make the text fields work in mobile browsers? (Currently the software keyboard won't open when you put them into focus.)

Are you trying compose multiplatform experimental web? then touch is not supported yet. For your help: https://github.com/JetBrains/compose-multiplatform/issues/3491

I'm not sure it's a touch issue. Buttons work fine on mobile, and you can click on text fields to bring them into focus.

are you using compose html or compose multiplatform?

Multiplatform.

There’s a lot of known issues with TextFields in Web. This issue from a few months ago says that the team is “getting closer” to making these updates, but I don’t know if any actual work has been done yet

Guess I'll check out the dev branches.

Compose for Web with Canvas rendering and Wasm is very experimental now. First of all we are focusing on Desktop, and iOS parts. If you need Compose on mobile, you can join to #compose-ios chat

@Dima Avdeev I'm aware of that. What if I wanted to contribute to the project? What would be a good start?

Here we have instruction to setup environment: https://github.com/JetBrains/compose-multiplatform-core/blob/jb-main/MULTIPLATFORM.md
