If you're having trouble receiving payouts to your PayPal account, it's usually an issue with your PayPal account itself.
You can try re-linking your account first, but you may need to contact PayPal's customer service if the problem isn't resolved.
To re-link your PayPal account:
Go to Settings > Payout methods
Select the Re-link option for PayPal
Alternative: add your bank account
Alternatively, you can add your bank account to Poparide instead instead and receive payouts directly to your bank.
