PBRIS doesn't work in edge on ipad

Hello ElenaSv​ 

• All third-party browsers on iPadOS (including Edge and Chrome) use Apple's WebKit rendering and networking engine under the hood, meaning an engine-level breaking change in iPadOS impacts all browsers identically.
• Modern iPadOS versions enforce strict TLS cipher suites, stricter certificate validation rules, and enforce Enhanced Tracking Prevention/sandboxed cookie handling that frequently breaks on-premises Windows Integrated Authentication (NTLM/Kerberos) and internal redirects.
• In iPadOS Settings, go to Edge (and Safari) and disable Prevent Cross-Site Tracking.
• In iPadOS Settings under Edge/Safari Advanced options, check if Private Relay or any experimental WebKit features are enabled and toggle them off.
• Verify whether the PBIRS portal SSL certificate uses complete Subject Alternative Name (SAN) attributes and SHA-256 signatures trusted by Apple's strict certificate trust store.
• Clear the local cache, stored credentials, and website data inside the Edge app settings.
• Test accessing the portal directly via the official Microsoft Power BI Mobile app for iOS/iPadOS rather than mobile web browsers, as the native app uses dedicated authentication brokers tailored for Report Server endpoints.
