Power Apps Length must be between 0 and 10000 error

I have a column in Dataverse that I have set as a multiline text field with 30000 characters. I have a portal where a user can input up to 30000 characters and save it no problem. I have a form on a screen in Power Apps that contains an edit/save button. The form default populates the 30000 characters into the field, but if I press the button to edit that field, I get the "Length must be between 0 and 10000 error". The form mode is multiline, I've tried setting the Maximum length attribute, but it still gives me that error. Documentation suggests that over 1,000,000 characters can be stored in a multiline column. Any ideas why I cannot seem to save more than 10000 characters in the form?

Hi @MarieAS

Are you storing the field in Dataverse as a Rich Text Field? If so then you are going to have a significant amount of characters that are going to be HTML characters within the 30,000 characters of the field. In my example 6,710 characters exploded to 23,171 characters with the HTML.

Not sure this is your issue but might be causing the problem...

Can you use the Len function and see how many characters are there? Is it really more?

Thanks @dpoggemann and @shashankbhide for your replies. I think the solution was to do a hard refresh on the Power App. I did a copy and paste into Word and did a char count and was confident that the char count was accurate. Good idea about the RTF, I hadn't thought too much about that, but it was just a plain text field.
