Hello.

Those dependencies worked fine. Thank you. I would suggest updating your ionic starter templates to use these newer dependencies to avoid further confusion.

@JoeBoxr Thanks for confirming! We're actually going to look to see if this is something we can fix on older versions since we are looking to support all versions of Angular 8. 🙂

I discussed this with the team and we have already begun requiring 8.2.x as the lowest supported version. I'm going to close this since we have a PR for the starters to update this: https://github.com/ionic-team/starters/pull/1079/files

Thank you!
