Hi there! I understand you're having trouble enabling online payments in the TymeBank app, and when you switch the option on, it reverts to off by itself. Let's get this sorted out.

To start, could you tell me if this happens every time you try to enable online payments? Also, have you recently updated the app or made any changes to your device settings?

In the meantime, here are some initial steps we can try to resolve this:

1. Check your internet connection: Make sure you have a stable internet connection, either Wi-Fi or mobile data.

2. Clear the app cache: Sometimes cached data can cause issues. On your Android device, go to Settings > Apps > TymeBank > Storage > Clear Cache.

3. Update the TymeBank app: Ensure you're using the latest version from the Google Play Store.

4. Restart your device: A simple restart can refresh app processes.

5. Check for any security restrictions: If you have any security apps or permissions restricting TymeBank from saving changes, those could cause the setting to revert.

If after these steps the issue persists, it may be due to app or server-side settings. Sometimes, if the bank detects unusual activity, online transactions can be temporarily disabled for security reasons.

Let me know which steps you've already tried or if anything changes. We can then look deeper into advanced settings or account status to fix this.

Are you comfortable performing these steps now?
