On my RUTX11 after upgrading to RUTX_R_00.07.00 the web-ui is unusable.
Uncaught (in promise) TypeError: c.a.find(...) is undefined
Uncaught (in promise) RangeError: invalid time zone in DateTimeFormat():
In order to get further I opened the developer console and delete the "div.spin-overlay" and "div.spin-content".
Other pages e.g. https://126.96.36.199/#/status/system do not seem to have this problem.
