How can I use the same email for multiple stores and solve iPhone viewing issues?

Topic summary

  • Goal: Use one email address across multiple Shopify stores to enable a single login and then select the desired store. Current setup: two stores already share one email; a third store uses a different email. When attempting to change the third store’s email to match, an “email already in use” error appears.

  • Secondary issue: On iPhone (Apple) devices, the site freezes and pages can’t be viewed, while non‑iPhone devices seem unaffected. The exact cause is not provided.

  • Request: Help with consolidating store emails under a single login and troubleshooting the iPhone‑specific freezing problem.

  • Status: No solutions, diagnostics, or official guidance provided yet. No attachments or code shared. Open questions remain on Shopify’s policy/limitations for using the same email on multiple stores and the root cause of the iPhone rendering issue.
