It's good to have you here, @usermhamill.
Let's ensure to show your missing supplier's to its designated window.
Before anything, I'd like to know if you're trying to view them on your computer or phone. Also, ensure to log in using the correct account since the "Vendor" term is used by other regions.
Let's perform some basic troubleshooting for QuickBooks Online (QBO) that was logged in via the web. This will help us determine if this is a browser-related concern. Also, this won't store cache files which causes odd behaviors.
To start, access your QBO account via a private browser. Feel free to follow the shortcut keys below:
- Google Chrome: press Ctrl + Shift + N
- Mozilla Firefox: press Ctrl + Shift + P
- Microsoft Edge: press Ctrl + Shift + N
- Safari: press Command + Shift + N
Then, view your supplier's list there. Once this works, clear the cache of your default browser to remove accumulated data files. Also, you can utilize another supported browser or device if it doesn't work. This happens when the current one you're utilizing has a temporary issue with the program.
However, if you're using a phone, I recommend logging out of your account. Then, update the app and sign in again. If this doesn't work, we can refresh the app and phone's data.
For iOS devices:
- Click the Settings, then General
- Tap iPhone Storage, then go to the QuickBooks Online app.
- Select Offload App to free up storage without deleting your app's documents and data.
For Android:
- Select More Options of the three horizontal dots, from the Menu icon symbolizing the burger sign.
- Click the Setting tab, the Refresh Data.
- Tap YES to confirm.
