I purchased my bud pluses back in March of 2020 and they worked great. Recently the ran out of battery life. I put them in the case and left them for 2 day before charging with the cord that was provided at purchase. Case shows a green light outside and inside of case. When removing the buds I do not get any sound or response to touch. I unpaired from phone and now can not connect them through Bluetooth or through wearable app. Help.
