Why can't I sign into my ecommerce app on iPhone?

Shopify Discussion

Topic summary

Issue: On iPhone, the Shopify app’s login page fails to load the CAPTCHA (anti‑bot check), showing an error suggesting an ad blocker is interfering. Disabling ad blocker didn’t help.

What was tried:

  • Reinstalling the Shopify app (no change).
  • Verifying login on other platforms: works on desktop (PC) and on a Samsung phone.
  • Confirmed iOS and app are fully updated.

Reported workarounds (mixed results):

  • In iOS Settings > Safari > Privacy & Security, turn off: “Prevent Cross‑Site Tracking,” “Block All Cookies,” “Fraudulent Website Warning,” and “Check for Apple Pay,” then reopen Safari; one user reports the app then logs in successfully.
  • Close the Shopify app, log in via Safari directly, then reopen the app; for one user, the error disappeared and login worked.

Conflicting feedback: At least two users report these steps did not resolve the issue.

Status: No definitive, universal fix. Evidence points to iOS/Safari privacy settings affecting CAPTCHA loading. Discussion remains open with unresolved cases.

Same problem happened to me, I solved it.

Go to iPhone - Settings - Safari - PRIVACY&SECURITY, turn off all below 4 items including

“prevent cross-site tracking”

“block all cookies”

“fraudulent website warning”

“check for apple pay”

then reopen Safari, then you can successfully login on Shopify app on your iPhone.
