The all dates column in banking wont let me select day , month, or year. The all dates column just flashes when i choose it. Why ?

Hello, Saters.  

You'd got me here, and I will ensure that you'll be able to change the dates of your transactions on banking pages in QuickBooks Online.  

Let's logging your account using Private window/ Incognito mode. Cache and internet files disrupt and cause unusual behavior.  

Here are the hotkeys for browsers:

• Google Chrome: press Ctrl + Shift + N
• Mozilla Firefox: press Ctrl + Shift + P
• Safari: press Command + Shift + N

If it works, go back to your regular browser and clear its cache. These caches of data are essentially junk files and can be safely deleted to free up storage space. Otherwise, switch or use a different browser. 

I want to make sure everything is taken care of for you, so let me know if you have any other issues or concerns by leaving a comment. I'm always happy to help. Have a great day!
