Hello, @Václav1
Thank you for your post and welcome to our Community Help Forum!
I am sorry to hear that you're not able to send or receive payment. I would request you to try using a different device, preferably a laptop or desktop, and switch browsers before sending payment. If it still doesn't work, check if you have any limitations on your account. If you do have limitations, here is how to remove limitations.
If you don't see any limitations and still facing issues withdrawing funds, I'd recommend reaching out to our Customer Support teams by clicking "Help & Contact" at the bottom of any PayPal page for further assistance.
I hope this helps!
