Can’t send multiple likes to followers activities.

Up until recently I could fire off kudos to all the people I follow by clicking a button near the top right (online). When I click it now, it says I have sent kudos to all but this is not the case. It might be an add on app that I have linked to Strava that allowed me to do this but I can’t seem to find out which. 
This is not to be confused with sending kudos to those who took part in the same activity as me as that works fine.

Any suggestions please?

Thanks for your response. Their answer to me was that it’s a plug in feature from a third party and that they unable to assist.

This seems to be a recurring issue. Strava says it’s been fixed, but not everyone seems to agree.
