Vagabond8630 Factory reset the buds following the instructions linked above, and re-link it with the BT settings. That should remove the Multipoint setting from the app, and I assume it would also disable the setting toggle itsel
I didn't get around to trying this but I don't believe it will work as I'm pretty sure multi-point is on by default.
I managed to turn it off by pairing the buds to my work Samsung device running stock. This did have the settings for multi-point and auto switch, both of which I've now turned off.
I'm now having the wonderful issue of the buds only want to connect to a device that's been told not to automatically connect. Phone in range and ready available to connect? Let's show a prompt on the laptop instead. In the middle of a call on your phone? No worries buddy we're just gonna disconnect and try and connect to the laptop real quick.
Anyway rant about bluetooth aside, I've resolved the issue but it's only brought on further bugs.
I really hope we see either major improvements or an outright replacement to bluetooth in coming years.
