Hello, @useraccounts35.
Thanks for posting here. May I know if you encounter any error messages when uploading attachments in QuickBooks Online (QBO)? That information is a great help so I can find you a timely solution.
In the meantime, let's access your QBO account using a private browser and upload the attachment from there. There are times that the stored cache and cookies can be damaged and cause problems when opening the QBO program. To start, here are the shortcut keys you can use:
- Google Chrome: press Ctrl + Shift + N
- Mozilla Firefox: press Ctrl + Shift + P
- Microsoft Edge: press Ctrl + Shift + P
- Safari: press Command + Shift + N
Once signed in, upload attachments again. Let me guide you on how:
- Open the desired transaction.
- Then, select Attachments.
- Browse and choose the document you want to attach.
- Click Open and then Save and close.
If this works, go back to your regular browser and clear the cache. This will remove the stored cache or cookies to refresh your browser. If not, I suggest using another supported browser.
