I'm asking them return crypto to my wallet
If it's based on government sanctions, it may not be up to Kraken (but I'm not a legal expert on international law).
Kraken disabled the legacy interface. The new interface uses 100% CPU on my old laptop, and slows down my entire system. That's a terrible design choice
Change browser that will most likely help. Plenty of ones to try. Chromium (de-googled version of Chrome), Chrome, Brave, Firefox, Opera... Or upgrade laptop lol. What kind of speccs do you have??
