I’ve tried to get into your staking Importing using my mobile phone browser, I've clear cache, but it still didn't work for me, I've been using this device on other projects, I don't know why I am having this challenges with yfdai.
Any possible advise?
If you are stuck using mobile, try using Imtoken wallet. It can use same seed as your eth address on metamask and has less issues. Metamask has had problems since its most recent update. I still recomend using a PC if at all possible though
