Hi @tiagosan
I think I know what happened. You probably ran expo run:android or expo run:ios at some point.
That has the side effect of generating the native android and ios directories in your project, which effectively turns it into a bare workflow app. I avoid using expo run:* for this reason. expo run:* can be useful if you’re debugging build issues, or if you’re developing native code as part of your app, but for a normal managed workflow app it is not necessary to use expo run:*.
If you want to get back to a managed app, see the following: expo.fyi/prebuild-cleanup
The main thing is to delete the android and ios directories.
