Working with the HTML Text control is challenging due to the " " an Concat-required "&" or "," mixed with all the HTML tags <this> and <that>. Its just too many symbols to contend with (IMHO 😉 ).
Please consider simplifying things by using a Markdown-capable rendering engine so we can quickly do things like:
# Report from user.Text
- Item 1: reportElement1.Text
- Item 2: reportElement2.Text
- Item 3: reportElement3.Text
### Wouldn't this be great?!
Thanks for all the hard work @powerapps Team!
