I have two official bands and a bunch of knockoff sport loops because Apple gave up on making ones that look nice, so it’s not a big deal to me if they change the connector. I’m not planning on upgrading from my Series 7 for a couple more years anyway, so it’s not like I’d have to get rid of my bands in the first place.
AdGuard works well for me. It also let me block ads in most apps. You can usually get a decent lifetime license for a bunch of devices (I believe 5) at StackSocial.
EDIT: Just checked, and yeah, really good deal running right now: https://www.stacksocial.com/sales/adguard-family-plan-lifetime-subscription
