Not syncing with Apple Health

Hello, I'm using the latest version of Sonar (as of today) with iOS 18.4.1. The app is struggling to connect with Apple Health, it keeps getting an error saying sync wasn't able to finish last time. I keep the app open for several minutes, at some point the progress bar dissapear but without syncing. I really love the UI and planning to subscribe, but this error is super annoying. Photos attached, also sent a log.
