Pairing Bluetooth on my Sandisk Clip Sport

I have tried multiple of times with all kind of ways  to solve this; upgrade of firmware, reset, pair and unpair with the same result all the time that the connection works for a couple of minutes or up to 30 minutes and then the next day it’s repeat itself. It’s so frustrating to start the running excersie and then after a short while realize that it’s loosing connection to the media player. Since we all are experince the same or simillar issue and we have differnt headset it clearly has to be something with Sandisk Clip Sport Plus and a new firmware is clearly needed. Can we get any offical info from Sandisk regarding this issue?
