Welcome to the Community, @nadav-ecocentre-.
Let's get this sorted out so you can enter your timesheets successfully.
You'll be able to save timesheets even if the Choose a Donor field is blank and unchecked the Billable (h/r) checkbox. Since you're getting an error saving your timesheets without that information, let's try logging in to QuickBooks Online (QBO) using a private browser. There are times that the browser stores frequently accessed data, thus causing QBO to act weirdly. Press this shortcut key on your keyboard to open a private browser:
- Google Chrome: Ctrl + Shift + N
- Mozilla Firefox: Ctrl + Shift + P
- Safari: Command + Option + P
If this works, it means that you need to clear the browser's cache so the system can start fresh. If you get the same result while using a private browser, I recommend switching to a different one.
