Does anyone have a problem when entering mileage quickbooks and the system is slow and crashes?

Thank you for posting here in the QuickBooks Community, @fagank450@gmail. I'd be glad to help keep your QuickBooks Online running smoothly. 

For the best performance, it's generally recommended to use Google Chrome. If the issue persists, you might want to close other open programs or browser tabs that you are not currently using to speed up QuickBooks Online.

Each program or tab in your search engine uses your system's resources, and if too many are open, this can cause QuickBooks to run slowly.

However, if it's still running slow, we can do some of the basic troubleshooting steps by accessing your account in a private window. Here's how:

• Google Chrome: Press CTRL + Shift + N.
• Safari: Press Command + Shift + N.
• Mozilla Firefox: Press CTRL + Shift + P.

If this works, consider clearing again the regular browser's cache so the system can start fresh. But if you get the same results while using a private browser, use a different browser app instead.

I'm only a post away if I can be of additional assistance or need more help with QuickBooks mileage. I'll be around to keep helping. Wishing you a wonderful rest of the week.
