This request came from one of CA Secure Cloud customers, it asks for formal support for Safari browsers.
In response to this Idea submission, CA Secure Cloud has changed its approach to supporting Internet Browsers. It now recommends two Internet Browsers in the Tenant Administrator Support Matrix and otherwise permits use of other browsers subject to the new Compatible Internet Browser Support Reasonable Commercial Effort Statement.
After review the product team decided to wish-list this idea so that it can be considered for implementation in one of our future releases.
Please note, supporting Safari browser alone will not affect how well the UI is rendered on small screens (e.g. on smartphones). This is because the current UI design is optimized for desktop experience.
