Hi there! I understand that you're having trouble getting the OMRON connect app to sync even when you press the sync button. Let's work through this together to find a solution.

First, can you tell me a bit more about your setup? Specifically, what device are you trying to sync with the OMRON connect app? Also, have you had any changes to the app or device recently, like updates or new installations?

In the meantime, here are a few steps to check:

1. Ensure Bluetooth is Enabled: Make sure Bluetooth is enabled on your device and that it's connected to the OMRON device.

2. Check Auto-Sync Settings: In the app, tap on the (...) sign, go to Profile, and then Connected Devices. Ensure that Auto-Sync is turned ON. This feature allows the app to sync data automatically from your monitoring device every few minutes.

3. Restart Devices: Sometimes a simple restart can resolve many syncing issues. Try turning off your OMRON device and your mobile device, then turn them back on.

4. Remove and Re-pair the Device: If you still can't sync, you may want to remove the device from your connected devices list and then re-pair it. Make sure to follow the pairing instructions specific to your device model.

5. Check for App Updates: Make sure that you have the latest version of the OMRON connect app installed.

If you've already tried some of these steps, please let me know, and we can look into more advanced troubleshooting. Following these guidelines ensures we cover all the essentials before delving deeper.
