Revolut bank has been removed from PayPal account after transaction. Can't add it again.

My Revolut bank was removed from my paypal account after I did a transation (many times it was working well) but this time I got an email : "A recent transaction with your bank account ending in **** didn't go through. As a result, we've removed this bank account from your PayPal account. To re-add this bank account to your PayPal account, please confirm with your bank that the account information is correct. Otherwise, you can add a different bank account. We apologise for any inconvenience this may cause."
  But in fact the money came through to my bank,
why it was removed from my account and why I can't add it again??  
It is not allowing me to add it back to my account.
In the transaction section of this particular transfer to my Revolut bank it is showing that "Estimated arrival in bank account 10 Jul"  but in fact it is already there. What happened? It shows that "Your transfer is on its way".

Is it PayPal error?

Is it a virtual / digital bank or one with physical branches?

I have to clarify now what have happened with this after I was contacted by PayPal Ireland. 
So the problem was with different transaction using the Revolut bank when purchasing from Aliexpress. The payment was declined by Revolut bank Ireland when I was using bank transfer as a default payment type. It was okay when you use credit card instead of bank transfer. So as a security measures PayPal have removed my Revolut bank from the list also not allowing to withdraw money to it when I was during that transaction process (but it go through before mu Revolut bank account was blocked by PayPal). You have to contact PayPal to re-enable this bank again and you have to agree to the terms they will tell you over the phone then you can add this bank online again.
