https://ssl.google-analytics.com/ga.js Label not found error with MS Edge

Question

On 8th March 2017 I started to see js errors coming out of Google analytics with the error message "Label not found" being caught by my window.onerror handler. It seems to only affect the MS Edge browser. Has anyone else seen this problem?

Answer 1

I was able to reproduce this intermittently using a clean install of MS edge using the stable edge virtual machine (v 14.14393) provided by Microsoft.

In the end I upgraded from the legacy ga.js integration method to the universal one using analytics.js as per these instructions:

This fixed it, so I believe this was a bug introduced by Google analytics on or around the 8th March, but that only affected old ga.js integration.
