Experiences with FW 15.31… is it worth it?

I have not experienced any negative issues with the new FWi (updated yesterday afternoon). I will be testing a run activity this morning.

Everything seems to be working so far. In addition to the stated bug fixes and improvements, they even increased the font size of the data fields in the Iron Grit watch face.

However, the entire user interface seems to be a bit more laggy. It's not as smooth as with 13.37 anymore. Not a major issue, but quite noticeable.

so it's happening beyond the Iron Grit watch face (the laggyness)? 

I'm still on the fence here. when I got my watch with FW10 (or 11), it was awfully laggy and I hated it, but thankfully, upon installing FW13.35 (I bought it 2 months ago), the responsiveness was much better. I wouldn't want to go back to the behavior I had right out of the box.

It's not nearly as bad as when the Fenix 8 was launched. But it is noticeable. If a slightly more laggy UI would bother you, I'd wait for another bugfix...
