I am trying to upload an attachment and it is stuck under "Uploading...".I have tried updating google chrome, using incognito, clearing my cache.Anyone can help?

Thanks for letting us know, tsktsksg. Let me help provide details when uploading file attachments of your transactions so you can have more organised recordkeeping in your account.

In QuickBooks, some specific attachment file types are supported by the program to enable uploads to your transactions. Invalid characters can lead to server errors. To avoid these issues, make sure this only contains accepted characters from the lists below:

• Alphanumeric: A-Z, a-z, 0-9
• Comma: ,
• Dot or period: .
• Question mark: ?
• At symbol: @
• Ampersand: &
• Exclamation point: !
• Number/pound sign: #
• Single quote: '
• Tilde: ~
• Asterisk: *
• Space: ( )
• Underscore: _
• Minus sign/hyphen: -
• Semi-colon: ;
• Plus sign: +

If the issue persists, it's best to contact our Customer Care Team to further investigate this issue and provide additional details in resolving this matter. I'm also sharing this resource for more insights: Add or delete attachments in QuickBooks Online.
