Large cross-platform native builds generally, not just mobile, kinda suck on the usual cloud solutions. The cloud stuff's amazing, performs well-enough, and is easy to configure if your workflow is... containers, and that's all. It gets rough in a hurry once you're much outside that, and especially with large (=long build time) apps. Many can accommodate native builds, but for anything non-tiny you'll experience slow builds or go over plan limits (and see spending skyrocket) in a hurry. Anything that requires large assets at build-time, or anything else for which it's nice to have persistent state between builds, is right out. You'll end up spending a bunch of time (=money) re-configuring your build to fit the tools, so performance is merely bad and not astonishingly, uselessly bad. You're also more likely, with native builds on cloud CI, to run into "yeah, we support that! (I mean... we shipped it, anyway, pay no attention to all the bugs and rough edges)".
