Is Microsoft D365 stopping support to Safari in future?
Hello,
Regarding your questions.
You can use Dynamics 365 with the Safari browser for almost all of the tasks.
docs.microsoft.com/.../supported-web-browsers-and-mobile-devices
But for PowerApps portals Studio no, for that only chrome based browsers
docs.microsoft.com/.../supported-browser
As far I'm aware Safari will continue to be support for Dynamics, although for not its not supported for the PowerApps portals Studio
