The problem you are experiencing is usually due to a browser caching issue.
Samsung Devices
Recently Samsung has released an update which, on many devices, has changed the default browser to Samsung Internet. This new update is causing issues for a wide range of apps whereby if there is a Single Sign-On feature within the app, this feature will not work or will stop working very quickly after use.
To rectify this, we will need to change the phone's default settings to use a different, more robust browser.
Could you please follow the below steps and let me know if this works for you;
- Close down the Weduc app fully so it is not running in the background
- Open the Settings menu on your phone
- Select Apps
- Select Default Apps
- Click on Browser
- Change the selection from Samsung Internet to Google Chrome
- Close Settings
- Open Weduc and attempt to access Weduc Payments again
Other Android Devices
