Issues Entering two or more timesheets using the web app.

Good afternoon! Thank you for bringing this to our attention, @davidtps. We definitely want tracking time to be seamless and quick. I have a few questions to clarify the issue you're experiencing. 

Is this error happening to other users on different computers? Have you tried a different computer or browser and does the error appear there? When did you start experiencing this?

While I take a look and see if there are any known issues related to this, I'd love to give you some basic browser troubleshooting that typically fixes problems like these. 

1. Clear cache and cookies. (This article is for QuickBooks Online but the same steps apply).
2. Try a different browser.
3. Use a private/incognito window.

Let me know if any of those steps helped. I'm looking forward to getting that extra information from you so we can get you taken care of!

This is happening to all users using the web app. First time we noticed was about two weeks ago.

1. I have cleared cache and cookies and we get the same issue.

2. I have tried a different computer and 3 different browsers: Chrome, Edge and Fire Fox.

3. Incognito window gives me the same issue.

I do appreciate you for performing the browser troubleshooting step provided by my colleague, davidtps.

I'd suggest contacting our Phone Support Team again so they can open an investigation about the error you're seeing. Just click here and select the Chat now link. I'll also share the article about Timesheet setup: QuickBooks Online and TSheets as future reference.
