Has anyone else noticed a dramatic dropoff in steps?

Pic related, but I noticed this morning that as I was going around my home, barely anything, and it was not counting anything when I was exercising on my indoor bike.
I thought it was weird, but nothing serious, but then I went for an afternoon walk and what normally takes ~10k steps took fewer than 5000. The flower count seems the same, 7700 for my normal walk is about right, it's just the step count.

Nothing has changed on my side, it's just weird that all of a sudden I had such a drop of. Just me?
