Does not recognize email address even though I have purchase receipt via itunes
Hi @nilssonic, welcome to the forums!
You don't need any license info for the iOS version of 1Password, because it's tied to your Apple ID and installed through the App Store. Where are you being asked for a license? If you're using 1Password on a Mac, please note the Mac version is sold separately from the iOS version.
If you're seeing a Trial Expired message in 1Password on a Mac, please take a look at this post from our Mac forums.
Hopefully that helps, but let us know if you have more questions.
