I feel like this must be a known issue to the manufacturers. My side button stopped working, but my Fitbit Versa 2 was few weeks out of warranty, so the only thing offered by the manufacturer was a discount on another one (and not a large discount). I went without a Versa 2 for a while and then found a great deal on a new Fitbit Versa 2 through a reputable company. Against my better judgment, I bought a new Versa 2. This one was only nine months old when the left button stopped working. In this case, since it was less than a year old and since I bought it through a reputable and known partner, I was able to get it replaced rather easily. I am waiting on the new one now, although I don't have much faith that the button will last on this one either. The only two Versa 2s I have owned developed the exact same issue rather quickly. (And, no I do not get my Fitbit wet, so it can't be that.)

I have dealt with this issue twice. The second time around my Versa 2 was less than a year old and I contacted customer support via chat and they offered me a replacement or a discount on another Fitbit product.
