Hi! I understand that you're not seeing Real-Time Arrivals information in your DaBus2 app on your Mac (macOS 10.15.7). Let’s work together to troubleshoot this and get it resolved.

First, can you tell me a bit more about how you access DaBus2? Is it through a web browser on your Mac or are you using the iOS version on an iPhone or iPad? Also, have you noticed if the issue started recently or has it been ongoing?

In the meantime, here are some initial steps you can try:

1. Check Internet Connection
Ensure your Mac has an active and stable internet connection, as real-time data needs connectivity to work.

2. Refresh or Restart the App or Browser
- If using the app on iOS device, force close and reopen the app.
- If using a browser on your Mac, refresh the page or try clearing the browser cache.

3. Verify DaBus2 Service Status
Sometimes the real-time data feeds can be down temporarily. There have been recent reports of system downtime causing no real-time data, in which case the app falls back to scheduled arrivals only6.

4. Update the App (if applicable)
Make sure you have the latest version of DaBus2 installed on your iOS device; updates often fix connectivity or data fetching issues.

If the above steps don’t help, there might be an issue with the data feed from the transit service. I can guide you through checking advanced settings or viewing static schedules until the real-time service is restored.

Could you confirm how you access DaBus2 and if you have tried any of these steps already? That way, I can provide more tailored advice.
