So I just withdrew my slp a while ago. And it got my heart beating fast. I went to Ronin bridge to withdraw my SLP to metamask and the confirmation to transfer from Ronin to metamask took a staggering 30 minutes! Every minute that passed by seemed like an eternity and it felt as if my SLP would disappear.
So if you're gonna withdraw your SLP to metamask, be patient. It will push through one way or another. Just make sure that the address is correct.
