Items saved to Managed Metadata SharePoint Column are overriding data instead of adding it to the Managed Metadata column
When I save my data to a Managed Metadata column in SharePoint, instead of adding items to the column, it overrides whatever data was in that column.
Here is my scenario:
I have a dropdown field for "Technologies" in my PowerApp. I use "Submit Form" to submit the form to its SharePoint List. However, I also want the "Technologies" dropdown field to also save to another SharePoint list.
Say, for example, I choose "PowerApps" in the"Technologies"dropdown field and click save, it will save this on the SharePoint list:
If I select "Power BI" from the dropdown and save the form, I want it to add "Power BI" to the existing data (this does not happen using the Power App).
Instead, what happens is that "Power BI" overrides the existing data ("PowerApps").
