@v-jefferni apologies for delay.
I am trying to send an email with options per record to a recipient (email addresses, different one per record).
Problem 1: flow will wait for a response from previous email before sending the next (to a different recipient). What I want is to send all the records emails regardless whether a response or not and not have to wait.

Problem 2: As per above, I want to capture the response(s), in a SharePoint file. Format of response based on initialized variable earlier in flow (e.g. EO3Mth'):
formatDateTime(addDays(startOfMonth(body('EO3Mth')),-1,'MM-dd-yyyy'),'dd/MM/yyyy')
However, I get the below error message...
