There are a few reasons why this may have happened:
The app will ask you to sign in again once a month for security reasons so that we can ensure the safety of your account.
It will also log you out if you switch between browsers or devices for similar security reasons.
Lastly, it could log you out if you are using certain VPNs, but that is dependent on the VPN you are using.
We’ve put a lot of time, money, and resources into making our app as safe for our users as possible, and this is a measure we have added as an extra precaution. 🙌
