I'm here to ensure you'll be able to successfully export your report, asenco15.
To resolve the issue, let's access your QuickBooks Online account via a private window. This doesn't use the existing cache files, which makes it a good place to determine if there's an issue with the browser.
Here are the keyboard shortcuts:
Safari: Command + Shift + N
Google Chrome: CTRL + Shift + N
Mozilla Firefox or Microsoft Edge: CTRL + Shift + P
After signing in, export your report. If you're able to do so, let's clear the browser's cache. This improves the performance of the program.
If it doesn't work, I'd recommend using different supported browsers. They'll provide you the best and most secure experience with QuickBooks.
