Hi, jaz-de-vivo.
I want to make sure you'll be able to connect your PayPal account with QuickBooks Online, so let me help point you in the right direction.
At this time, there hasn't been other reports of users being unable to connect with the Paypal app. Since Community platform is a public forum, I won't be able to check your account without asking for sensitive information. For security purposes, it would be best to contact our Customer Care Team to ensure that you'll be able to connect with your Paypal account.
You can get our most-up-to-date contact number here: Get help with QuickBooks Online. Also, you can check out this link to get started with live chat support: https://help.quickbooks.intuit.com/prechats/offerings/QBOP-CHAT/15024/view.
I've got your back if there's anything else I can help with. You have a wonderful day!
