My app’s URL: https://crewlist.glideapp.io/
I have my app setup to generate a template of selected individuals from the picker page and combine them into the correct format on the Crew List page. From this crew list page you can either Copy or Share the crew list.
When I click share from my computer this will show up in my email client just fine. When I do it on my mobile phone (iPhone XR), it ends up showing all of the < BR > tags.
