Triangle on my Garmin Vivo move luxe watch

I have the same exact issue. Vivomove lux watch - intermittently won’t charge, gets the white triangle of death, new charge cord doesn’t fix it, Furthermore, it intermittently completely wrong re: metrics, acts up while swimming, can’t track my spinning activity, can’t see during daylight/sunny outdoor activity. Really disappointing for what should be such a high end piece of equipment. 
how do we fix this? 

Nobody from Garmin has ever informed us what the issue is.  Yes it’s a very expensive watch and worked for 2 years then dead.  Can’t get an answer.  I since purchased another brand and will never buy another Garmin product again 

Did you ever contact Garmin? I've had nothing but great support every time I've called them.

I did try some time back but gave up as I got no real response that helped from Garmin 

Same problem with me over the last two days. I could only get it to charge to about 30% and now I have the dreaded triangle when I try to charge it. 

Would you please email me too?

Same issue. Does anyone from garmin ever post feedback here?
