Glad to see you here in the Community, Dineskd,
I appreciate the things you've tried on your end to get past this issue. All the details you provided will help us narrow things down.
Our Support Team has already implemented a resolution for the unexpected error with the Connect to PayPal app. Since you're still experiencing the same issue, I'd recommend getting in touch with our QuickBooks Online Care Team.
There they can help you open an investigation to identify why you're still unable to post your sales transactions. Also, if you're unable to reconnect your bank, you may follow the steps listed below:
- Go to Banking at the left pane of the screen.
- Select Add Account and then search.
- Enter your financial institution's login information on the website and select Continue.
- Complete the extra security verification steps.
- Select Securely connect.
- Choose the bank emblem to the left of the account that you want to connect.
- Select the account type drop-down menu to choose the bank or account.
- You must choose either a Bank or Credit Card account.
- Select +Add new if you don't have an account created yet.
- Click Connect.
