Charging (bug?) Causes Device to Require "Reset"

Hello,

If I fully charge (I haven't checked it it happens on less of a charge) my edge 530 I have to hold power button for a while until the device beeps (20 seconds?) then do it again to get the device I boot/behave normally. Works as expected and sleeps fine until next charge.

Newest software with no connectiq apps/fields installed. 

Not a huge issue but seems like a bug? Totally reproducible.

Thanks!
