Problem: First email from PowerApps form is showing "Show HTML text here". The odd part is this is only happening on the first submission. Any other submissions go through as expected.
I've created a powerapps form for internal use. The form is basic requiring certain fields to be selected before a response can be sent. From there, I have conditions based on what is selected to send an email using "Office365Outlook.SendEmail". I made a separate page to draft the body of the email using an HTML textbox, and referencing them in the OnSelect property of Submit Button.
Below is the HTML body that is getting sent:

Below is OnSelect Submit Button:

Has anyone else had any issues with this and how can I fix? I was originally using Flow to send an email when a new item was created in sharepoint; however, the emails were coming from my own since I setup the flow with the submitter copied. I would prefer the powerapps option if I can get it to work 100% of the time!
Please help!
