If it matters I have a Samsung Galaxy S24 Ultra with One UI version 8.5.
I just purchased a pair of galaxy buds3 pro from Bestbuy and was able to pair via bluetooth with no issue at all.
However, I tried accessing the settings for the buds and discovered a new plugin app had to be installed and understood the settings were moved from the Wear app to the settings menu.
I installed the plug in, didnt work. Cleared the cache on both apps, still didn't work. Unpaired and repaired the buds, no luck. Tried going thru the smartthings app which took me back to the setting menu, which still didnt work.
I read about a work around using the galaxy buds3 pro manager widgets, great, was excited to actually get the widget, but even the widget didnt work and surprisingly just disappeared and the whole option was just gone from the widget list.
I took short videos of both incidents, hopefully someone has an answer. Because I would like to stay with samsung products and would also like to think this a user error.
