Problem organising a report.

I've just followed Andy's video on this page: https://www.youtube.com/watch?v=_FA5-uMV8u8, which explains how to make a report. However, in my version of Ninox (for iPad), absolutely nothing works as it says. For example, if I create a formula, this is not done directly in the field, as in the video, but opens a window from which you can access the formula panel.

This formula is displayed in the window, then in the report field. If you want to change the formula, open the panel again and it has disappeared. Any changes made are not reflected in the field. You therefore need to delete the field and create a new one.
In addition, if you want to type a text, the window opens again, but the text does not appear in the field.
For tables, there's no way of adjusting the width of the columns as it does in the video. Even if you try to select it, nothing happens, whereas in the video the column turns blue. I feel like I'm working with a completely different programme.
