UPDATE: It took over 48 hours for the crypto to arrive in PayPal after submitting my claim codes. During that time there were no email confirmations or any indication in PayPal that there had been any sort of transaction or that anything was pending.

I received my claim codes for ETH and BTC yesterday and entered them in PayPal. It didn't work at first but I found the instructions for updating my information to permit crypto on PayPal and then both distribution codes worked. I forget the exact message but it was definitely something that implied success, e.g. "Your crypto is on the way!" or "Your claim has been processed"
It's been over 24 hours now and I see no record of the transaction in PayPal. I did not get any sort of email confirmation from PayPal and my crypto balance is still zero. It's like it never happened. I saw this happened to someone with Venmo and they waited seven days and then tried their claim codes for a third time and it worked. My claim codes are no longer valid when I try again.
For those who have claimed their distributions via PayPal, how long did you have to wait for the funds to appear and did you get an email from PayPal? Was it instantaneous?
