We started offering Internet Explorer instances in June 2014. Almost 3 years later, less than 0.01% of the screenshots have been done one of the 4 Internet Explorer instances we have available.
We think it is better to focus our efforts and resources on the Chrome and Firefox desktop browsers, as well as the Android and iPhone mobile instances.
We will hide the Internet Explorer instances from the dashboard in the next 2 weeks. They will still be available through the API. The instances will be completely removed by April 16th.
Please contact us if you have any concern.
