I can't see any info on my app, no clients sales or anything

Let's make sure that you're able to see your data when using the app, dallos.services.

Can you also tell us if you're having the same issue when logging in to your account on the web version? 

If you're only getting it in the mobile app, make sure you're using the same credentials you used when signing in on a web browser. You can also click the "I forgot my User ID or password" link in the app.

Then, follow the instructions on the email to reset your password. You can also refresh your data in the mobile app if you're already using the correct login details. Here's how:

iOS

1. Go to Menu ☰ and tap Help & Feedback.
2. Tap Refresh Data.
   Note: A message appears “Caution. If there was a problem getting your latest QuickBooks Online data, you can refresh it now. It may take a few minutes.”
3. Tap Refresh to confirm.

Android

1. Go to Menu ☰ then tap More Options ⋮.
2. Tap Settings then Refresh Data.
3. Tap YES to confirm.

Aside from that, you can also restart your device and log back in. Then, check if you can now see any data.
