I had this issue on OneUI 8 and still have this on 8.5. The Bud 3 Pro settings page doesn't open from the settings while there is no option in the Wearable app. I tried reinstalling a few times the Buds Manager but nothing works.
The wearable app does not apply to the buds anymore, only the watches etc. When the buds are active, they should auto-connect to the phone and show up at the top of the settings page. Also, the buds widget can be added (and resized) to the home screen that has the exact same functions when opened. If they do not appear, then clear out the Bluetooth devices.
Settings/General management/Reset/Reset Wi-Fi and Bluetooth settings then click reset. This will remove every Bluetooth paired device and any of them will need to be paired again, This will also reset the Wi-Fi connection, but that only requires a login back into the network. If that does not work, then open an error report in the Members app. Open the app, go into the beta then click "Beta feedback" and submit the issues using screenshots and even a screen recording if possible. Be sure the bottom is ticked "Send system data log" and wait until it is finished.
To help us investigate further, please submit an Error Report through the Samsung Members app immediately after reproducing the problem:
1. Open Samsung Members โ One UI Beta Program โ Beta Feedback. 2. Select Error reports and attach any relevant screenshots or screen recordings (if available). 3. Make sure โSend system log dataโ is enabled before submitting.
Important: For accurate log collection, please submit the report within 3 minutes of reproducing the issue.
We apologize for any inconvenience and appreciate your support in helping us improve the Beta experience.
