Replying to a review on App Store

Hi. Is there any way to answer reviews on Ubuntu App Store? My applications have bad reviews and I would like to fix the problems. The users does not report the issues on the right place; for them it is easier to post a bad review but this is not constructive. I see there are one bug addressed 8 years ago and a proposal for implementation on the app store. What can we do?

Thanks for the attention.
