I have created a multiple repeating table using the following blog: https://anjcerbolles.net/2020/08/02/repeating-tables-in-power-apps-using-sharepoint-list-form/
In the above blog, it lets me go the Edit Form and edit/delete the current items but doesn't let me add new items to the Child list.
I need the functionality where when I go and edit the form, it lets me edit/delete the old items in the child list but also let me add more items. Currently, when I go the "Edit Form" it displays value from the child list (Items is filtered the 'Child List') but it won't let me add new values.
If anyone has any ideas on how it can be done, it will be greatly appreciated.
