Daily Lucky Box coins nerfed down

I'm in Canada and I have 3 Daily Lucky boxes to open each day, after 0, 1000 and 2000 steps respectively.

It was common to get over 10 coins each, but recently it was nerfed down to almost half, getting around 5 coins each.

Anyone noticed the same?

The app has been nagging me recently to update which I didn't, in case the new update changes anything to the worse (if it's not broken don't fix it). Not sure if updating the app will help here.
