(The following is also present in Logic Apps which is where I originally found the issue before replicating in Flow)
When using the Send Email with Options action, if using more than 2 options the formatting in the sent email is a little odd. It would be good to have more control over how these options display i.e. stacked vertically/horizontally etc
Email with 2 options
Email with 3 options
We do not plan to allow the customization of the formatting of these emails. However, you can use rich text in the Approvals actions themselves (see here), and we plan on adding custom options to these actions (see here).
