I don't see anything when I try to log in on my iphone

If the screen turns black when you tap Log in in the Cosafe iOS app, try the following solutions.

Solution 1: Turn off "Block All Cookies" in Safari​

This is the most common cause. iOS Safari's Block All Cookies setting prevents the in-app login window from storing the data it needs, which causes it to crash silently and leave you with a black screen.

  1. Open Settings on your iPhone
  2. Scroll down to Safari
  3. Tap Advanced
  4. Toggle Block All Cookies to OFF

Then re-open Cosafe and try logging in again.

If you can't find the option, you can also go to Settings → Safari → Content Blockers and turn everything off.

Solution 2: Disable Accessibility settings (alternative)​

If turning off Block All Cookies did not help, try adjusting the Accessibility settings for the Cosafe app:

  1. Open Settings on iOS
  2. Search for or scroll down to "Accessibility"
  3. Scroll down and select "Per-App Settings"
  4. Add Cosafe to the list of apps
  5. Disable "Reduce Transparency"
  6. Disable "Reduce Motion"
  7. Open Cosafe and verify that the icons are now visible

If the issue persists, please contact our support team.
