Hi All

I am working on trying to update my Ionic App from 5 to 6.

I have installed Angular 12, which I believe can work with TypeScript 4.3.5. But I am getting the following error

` ERROR in The Angular Compiler requires TypeScript >=3.6.4 and <3.9.0 but 4.3.5 was found instead`.

This is the output I get when preforming an ionic info

```auto
