Plugin problem with Paypal Business

Hi,
I installed your plugin and tried to link my PayPal Business account in the plugin settings. However, the procedure has not been successful and I do not understand why.
The message said: “Your request could not be approved. you can submit a new request in 90 days after the previous one. in the meantime, you can still use your PayPal Business account to send and receive money.”
I didn’t send any requests, I just tried to link my PayPal Business account to your plugin.
Can you help me?

Thanks in advance for the help!
