What happened?

When running app_opensInterests() on CI, the test fails that it can't find the "Topics" text in the UI, however, running locally the test passes.

I've tried upgrading the emulators on Github to have hardware acceleration as I assume this is an issue with linking Github Actions + Emulators + Linux, but this didn't help.

I also tried setting a timeout to longer (5000ms), but this didn't help.

[JoseAlcerreca]

It's failing on robolectric, not instrumented. Probably because the screen is too small in the default robolectric device.

[JoseAlcerreca]

There must be a race condition somewhere because I was trying something else and I saw that adding

@GraphicsMode(GraphicsMode.Mode.NATIVE) fixes the test.

[JoseAlcerreca]

Logging off, for now I have no idea why it's failing on Robolectric, I don't think it has to do with the screen size. It looks like the app is not navigating to Interests at all.
