Hi @Milly ,
I think you can use a Condition control first, checking how many approvers are selected from PowerApps. If there is only one approver, no need to judge the first approval outcome.
So, in PowerApps you can create a Collection to include all the approvers selected in those Combo boxes before triggering the flow:
ClearCollect(colApprovers, Combobox1.Selected.Email, Combobox2.Selected.Email, Combobox3.Selected.Email, ...);Flow.Run(Concat(colApprovers, Email, ";"), ...)
So the Emails are passed to the flow, in you flow Condition control use split and length functions to make them in an array and check the number of Emails:
length(split(Ask in PowerApps, ';'))
Best regards,
