Each time I use Quickbooks I'm having to reconnect my bank account. This just started happening about a week ago. Is this a QB bug?

the big will be fix 

Thank you for reaching out to the Community, David. I appreciate you bringing this issue to our attention, and I want to ensure that we address this matter right away.

Could you please let me know if you are encountering any specific errors? Also, may I know what financial institution you are using? Have you tried accessing your online banking outside of QuickBooks Online? Any additional information you provide will be helpful in identifying the root cause of the issue. I also suggest that you check with your bank if they have released any updates.

In the meantime, to eliminate any errors or glitches that may be occurring in the system, I recommend using a private browser or incognito window.  Here are the keyboard shortcuts for different browsers:

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

Once it works, proceed to your regular browser and clear its cache to refresh your website's preferences. Also, note the system's supported browser for the best and most secure experience.

Lastly, I'm adding some articles that could help you manage and organize your bank transactions to ensure they go to the right accounts and prevent duplicates:

• Fix bank upload errors in QuickBooks Online
• Categorize online bank transactions in QuickBooks Online.

Please reply to this post if you have any additional questions about online banking. I'll be monitoring this conversation closely and will respond promptly once I have the additional information. I'm here 24/7 to assist you.
