I had been wondering if I was just losing grip strength. I workout 5 days a week. I also design and build houses for a living. I. E. Pounding shit into the ground all day.
I will say, the issue seems to be refrigerated vs. non For me. I occasionally drink the Vanilla cafe room temp. They open right up. I put bottles from the same box in the refrigerator and they are tougher.
Any how that’s just my observation. Found this thread online, knowing how this product is like software, constantly updating I just thought I would add my bug report.
