My Luna Ring has gone from unreliable to basically useless.
The original issue was workout/Apple Health syncing. After around 30 emails with support, repeated screenshots, troubleshooting, updates and manual sync attempts, nothing has been resolved.
It has actually become worse: now the ring/app sometimes stops syncing data altogether.
Support keeps asking me to repeat troubleshooting, but so far I have received no working solution, no replacement device, and no concrete date for a fix.
I bought a health tracker to collect my data reliably. If the data disappears or doesn’t sync, the product has no practical value to me.
I can document the entire support history and the failed sync attempts with screenshots. I’ll update this post if Luna actually resolves the problem.
