Thanks everyone for your experiences! It’s good to know I’m not the only one noticing this. And, not a big issue obviously in the grand scheme of things, but a little bit of a hassle / adjustment.
While it’s too bad about my other 3 bands, on the bright side, I enjoy the Nike sport loop now (the comfy one with the velcro, not sure if I’m naming it correctly) since the S10 lasts 24 hours so I only need to charge it once daily. With the S7 before, I couldn’t handle wearing this band often because of having to remove it 2 or more times a day to charge.
