There have been several reports to Ava Security of problems with icons displayed by our Reveal web UI, for example icons that are expected to be white will show up as grey:

The root cause of this appears to be incompatibility with some browser extensions that modify the CSS (Cascading Style Sheet) presented by the Reveal UI to the browser. One known example if the RingDNA Intelligent Dialer for Salesforce, however there may be many others.

Currently the only known solution is to temporarily disable the affected browser extensions whilst browsing the Reveal web UI, and re-enabling afterwards.
