I have an approve document by multiple approvers flow that is currently working. My intent was to have a column name "Approved By" and have all the names of the approvers listed in this "multiple line of text" column that I created. The option on Sharepoint online "append changes to existing text" is not available. I know there's a way to use "append to string/array variable" connector and also a way to concatenate the string. Not sure which way is more efficient. I'm unsure where to place them in my current flow. Please see screenshot of my current flow.
If your issue is that "Append text" is not available in the multi-line text box, you need to turn on versioning. Once versioning is turned on, you'll be able to turn on "append text" in the list settings.
