Brand new app - Can't perform a React state update on an unmounted component

[papadi]

When I'm creating a new app (npx ignite-cli new MyTestApp --expo) and run it on the browser without any modification of my own (yarn web) then I get this error in my browser console.

"Warning: Can't perform a React state update on an unmounted component. This is a no-op, but it indicates a memory leak in your application. To fix, cancel all subscriptions and asynchronous tasks in a useEffect cleanup function."

Any idea why? I cannot detect where it's coming from.
