If you get logged out of your account, you will need to get back to the login screen. Here is what you need to do:
Tap the menu icon (☰). Depending on your app version, it will appear either in the top-left corner of the Home screen or in the bottom-right corner of the tab bar
Tap 'Me'
Scroll to the bottom and log out to return you to the login screen
Tap 'Already have an account?'
Enter the email address you used to create your original account and follow the prompts
If Cupla does not recognize the email address, it could be that you originally created your Cupla account using your Apple ID. Cupla is unable to confirm this as Apple obfuscates the address, so please try this, before contacting support.
If you still cannot access your account, and your partner is on an iPhone, please ask them to follow these steps. (Sending a login link is available on iPhone only, and only once your account has an email address on it. If your partner is on Android, or cannot see the option, message our support team from the app and we will restore your login for you.)
Tap the menu icon (☰). Depending on your app version, it will appear either in the top-left corner of the Home screen or in the bottom-right corner of the tab bar
Tap [Partners Name]
Tap 'Share login link with [Partners Name]' and send the link via your preferred messaging application
You will simply need to open the link from your mobile device with the Cupla App installed for the link to work.
If you would rather keep the new account than go back to your original one, your partner is the one who has to act: they disconnect from your old account and then connect to your new one. See We look connected on my partner's app, but not on mine.
