I went for an outdoor run on the weekend. Normally I bring my phone and pair it my wireless earbuds (Galaxy Buds) and this works great. However my phone was jangling all over my shorts so I downloaded a bunch of music on my Fenix 6s pro. As soon as I started running, the music would randomly cut out. It was driving me nuts, so much so, that I went back home. A quick web search indicated that I needed to put my watch on my right wrist, as that will align with bluetooth on my earbuds. Problem solved and I was running again. Just an FYI if anyone else comes across this issue.
