Possible to previous version of K9 Mail?

On my phone the new version has issues. When I want to check for new mails, I have to swipe down multiple times to refresh the emails and often wait several minutes. If urgent, I have to use a browser and webmail to check my emails.
With the previous version the problem didn’t exist. When I swiped down, the emails were immediately refreshed.

Is there a way to go back to the previous version of K9 Mail?
