Hello, 

Just wondering if anyone else is experiencing this or if tp-link has any comment about it. Every ten minutes since 2:30am I've been getting the following email:

"Hi, 

We noticed a login attempt form an old version of Kasa app on an unrecognized device. Since Two-Step Verification is enabled, you'll need to update your Kasa app to the latest version to long in with a verification code.

If it wasn't you logging in, someone may be trying to access your account. You can change your password to secure your account."

From what I can tell my account hasn't been breached and the email address appears legit: no-reply@email.tp-link.com. Since I changed my password I haven't received any additional emails. 

Cheers.
