Hi Jonathan,

I tried to reproduce your issue, but I cannot reproduce it.

How long is the text that you are trying to copy?

This is what I tried myself:

I succesfully copied a multi-line field while using the 'text' type

I've used the following text:

this is a rather long text, don't you think so? I really do think it is long​ - line 1

this is a rather long text, don't you think so? I really do think it is long​ - line 2

this is a rather long text, don't you think so? I really do think it is long​ - line 3

this is a rather long text, don't you think so? I really do think it is long​ - line 4

this is a rather long text, don't you think so? I really do think it is long​ - line 5

Greetings,

Robert

To copy any kind of text, you can just use the Text datatype. it can contain more than 255 characters = multi line of text

Just another quick tip:

You can also use the 'Create List Item' action. You don't need to specify the 'field type' for a field in that action and it's far easier to configure (no need to enter any Office 365 information)

Thanks!
