I hope you can use other adapters instead of NativeDateAdapter. Checkout #141
@JelleBruisten Do you know this issue?
https://github.com/ng-matero/ng-matero/blob/be56972b01728970aef0bf398c5175fd55b801c9/src/app/core/bootstrap/startup.service.ts#L41-L50
Please logout and login again.
Can you provide a reproduce video?
Yeah, there has no file upload example. I have no backend upload service. Perhaps you can refer to the file upload demo of [this project](https://acrodata.github.io/gui/media-controls).
Please don't modify the dist files, you should modify the `src/js/core.js`
