Current Certificate is expiring. Hence created a new certificate and updated the SSO settings with the new certificate. The Request Signing Certificate and Assertion Decryption Certificate are updated with the new certificate.Getting error during SSO.

I am the system admin and Enabled the Lightning view in the Sandbox. Immediately the page is routed to an error page and displaying 'We are down for Maintenance'
I tried to login to the sandbox again and  it is defaulted to Lightning view and displaying the above error message. I cannot login to the Sandbox now.
Any ideas how to solve this problem and login to Sandbox successfully.

I logged into the sandbox  Salesforce1 mobile app successfully. It is defaulting to Lightning view. I dont find the option to switch to classic view in the mobile app.
I navigated to Setting-->Advanced-->Diable Lightning Logging. However even after logging back again, it is defaulted to Lightning view.
Any ideas in how to navigate to classic view is greatly appreciated.

Dear all,

We're looking at the various options of using Salesforce mobile (Salesforce1 application, SF1 Browser, Salesforce Classic in the browser) and are finding limitations with each:

Salesforce 1

• Overriding the "View" action on an SObject appears to have no effect at all in SF1 and the standard page is displayed
• The lack of ability to override the Edit action and then return to the normal edit page if the override logic requires it

Salesforce Classic in Mobile

• If you direct to the full Salesforce classic site in mobile (i.e. switching off the "Enable the Salesforce1 mobile browser app" setting), the UIThemeDisplayed variable still seems to think that the user is in SF1

Lightning Experience

• With Lightning Experience switched on and "Enable the Salesforce1 mobile browser app" switched off, the user cannot log-in on mobile
• With Lightning Experience switched on and "Enable the Salesforce1 mobile browser app" switched on, the user is directed to SF1, despite Lightning Experience being responsive to different screen sizes, etc.

Does anybody have any advice, answers or workarounds to these questions? It makes mobile development very difficult when the navigation behaviours/capabilities in the desktop and mobile version differ so wildly.

With thanks,
Andy
