I did claim them but when I tried swapping a part of UNI coins to ETH, the transaction had an error so it didn't go through. Sadly I lost gas fees. Then when I tried sending a part of UNI to Binance, the transaction got stuck so I decided to increase the speed but it didn't go well and the transaction failed again. Now I've lost more than 50$ on ETH but I still hope to swap a part of them because it would mean a lot!
