"Not sure it qualifies as a "huge" bug, it would depend on how many people bought a BoostCharge"
Considering Apple sell it on their site directly (at a not-cheap price), I would be surprised if they don't pull their finger out on this one. Shame it didn't make the last bug fix, but perhaps its a non-trivial issue.
" At this point I would suggest that you, and everyone else, that has a
Belkin BoostCharge contact both Belkin AND Apple and report the problem."
I'm sure Apple are already aware. It has been reported by numerous tech news sites.
" And if Apple asks your help by running a profile on your Watch for
testing volunteer for it.""
I would guess that it affects every Apple Watch S7 with 8.5.1. So I don't think Apple will have a problem regenerating the issue.
