used to work great, now doesn't work at all... I have CMF watch 2 pro, after the nothing X app got merged with CMF watch app, all was working perfectly, now I wasn't using the watch for few months for personal reasons. yesterday I wanted to pick up the watch again and can't pair the watch to the App properly, despite the pairing/binding process goes through, my watch don't show as connected, can't change my health information (age/height/...) any change gets instantly reverted. disappointment

Edit: At first i liked it but now its just constant bugs, pain to use with multiple devices, often only just one side connects. They released a newer one for 50% more price and is pretty much the same. There are better and cheaper options at this point. Not bad, looks nice and clean but definitely needs more settings that i assume would be easy to carry out. Needs proper EQ, a traditional one with frequencies, the current options are waaay overtuned to my taste.

Hi, Aron Boros. Pls. 1. clear the cache of the earbuds app. 2. Uninstall & reinstall the earbuds app. 3. Reset the earphone by pressing the pairing button till it lights to red (make sure the earbuds are inside the casing but keep the lid open). Or contact our support here: https://nothing.tech/pages/contact-support. Thanks!

It's a good app and well designed however, it would be great to have the ability to set the LDAC/LHDC playback quality and keep it persistent between uses. 'Best effort' is useless but being able to set 'better connection quality', 'balanced quality' or 'better sound quality' would fix these issues. It's a small feature but it was something that I could set (and it was persistent) in the Sony connect app (for my other earphones).
