Hello @FRANCESCO_CAMPISI,

Welcome to our community and thanks for reaching out to us about this issue!

This behavior often occurs when something in the IOS device or browser setup is interfering with the login process — typically related to cookies, network, or time settings. Before we take the more heavy-handed step of reinstalling the app, here are a few suggestions to try first:

  1. Clear Safari’s Cache and Browsing History
  • Go to Settings > Safari and select Clear History and Website Data. This will help remove any cached or corrupt cookies that might be interfering with the login process.
  1. Check Browser Privacy Settings
  • Make sure your browser isn’t blocking cookies or pop-ups. In Safari, this is usually under Settings > Safari > Privacy & Security. Disable options like “Block All Cookies” or “Prevent Cross-Site Tracking” temporarily.
  1. Try Logging in Again via ARC
  2. Switch Networks
  • If you’re on WiFi, switch to cellular data, or vice versa. This will often reset the DNS server being used, which may help resolve login issues.
  1. Verify Date and Time Settings
  • Go to Settings > General > Date & Time and make sure Set Automatically is enabled. If your device’s system clock doesn’t match the login request timestamp, it can silently block login attempts.

If all else fails, please try reinstalling the app from the App Store and attempt the login again.
