IOS 10 Bluetooth malfunctioning

Hello,

Since upgrading to iOS 10 some of my BT headset/speakers stopped working flawlessly ands I now have to enter bluetooth settings to manually connect my Beoplay A1 speaker most of the time when I want to use it and worse in order to make my Phillips Fidelio M2BT headset work I have to completely remove the device from the BT settings and then redo the pairing everytime I turn it on.

My Dali Zensor AX 1 speakers hasn't changed behaviour and still connect as soon as I turn them on.
