copy backup not showing any progress after 48 hours

I have some troubleshooting steps for you to perform so you can resume creating a backup of your QuickBooks Online (QBO), maxmartapp.

There are times that an issue like this occurs when we encounter a browser-related problems. I’ll lay out the process below.

First, let's log in to your QBO account using a private or incognito browser to determine if this is a browser-related issue. This mode allows you to use the most recent version of the webpage without storing data that might interfere with display issues and cause the page to freeze. 
 

Here are the shortcut keys for accessing incognito mode: 

• Google Chrome: Ctrl + Shift + N
• Safari 11 or newer: ⌘ + Shift + N
• Mozilla Firefox: Shift + Ctrl + P
• Microsoft Edge: Ctrl + Shift + N
   

If this resolves the issue, return to your regular browser and clear the cache to delete any temporarily stored files and browsing history. Over time, accumulated data can cause corruption; however, removing it should fix the problem. You may also want to use a supported, up-to-date browser to rule out any browser-related issues. 

In addition, you can refer to these articles for detailed steps on importing customers' data and answers to frequently asked questions, such as the file format used in importing for future use:

• Import customer or vendor contacts from Outlook, Excel or Gmail.
• Common questions about importing data to QuickBooks Online.

Feel free to reply to this post for additional questions about managing your files. I'll get back to you, maxmartapp.
