It's also a good idea to ensure that your device meets the minimum system requirements for the latest version of the WeChat app. This may include having a compatible operating system and sufficient storage space.

Overall, while it may be possible to use an older version of the WeChat app to pay for retainers, it's recommended to update the app to the latest version to ensure that you have access to the latest features and security updates.
