Issue

Users with email addresses containing periods (e.g., abc.def@gmail.com) are unable to login on mobile. The mobile client is stripping the period from the email address, creating a new account with the modified email (abcdef@gmail.com instead).

Details

• Affected email format: Emails with periods/dots in the local part (before @)
• Affected platforms: Mobile
• Behavior: Period is stripped during login, resulting in account creation with incorrect email
• Expected behavior: Email should be validated and used as-is, or user should receive an error if email format is invalid

User Report

I can't seem to login to my account with a period on mobile. I have an email like abc.def@gmail.com but on mobile it stripped the dot and made a new account abcdef@gmail.com
