Maps is now crashing the browser / tab in some instances when has been left open for more than an hour or so.
I am currently suspicious of the METAR auto-refresh code, as it appears to be the only layer triggering this issue for me. Another customer has reported that real-time reflectivity also causes this, however we have been unable to reproduce the issue with that layer on multiple test machines.
We are investigating this extensively and hope to have a fix posted soon. Thank you for your patience.
