tap tempo frustration

So i recently got a footswitch and i thought i might use it for tap tempo. Turns out you have to wait a couple seconds after you tap your tempo before you can start a beat… This was a really disapointing moment. When you tap tempo - beatbuddy starts showing bpm - and after you finish tapping it still shows bpm a couple more seconds and in that time you cannot start a beat.
Anyone noticed this? Is there a way to work around this?
