I have 2 smart phone, they are Samsung S8 Plus and S9 Plus. I have 3 new computer notebooks, Acer i5gen10 and Asus quite new. They cannot connect bluetooth to my Bar-48. I dont know why??? Please help. Whereas They can connect to all my other bluetooth speaker devices such and Klipsch RSB-14, Harman Kadon Go play mini, esquire, jbl flip4, Harman Kardon studio3, etc everything NO PROBLEM at all. I asked Klisch support team they just teach me to how to connect bluetooth and to resetting.
