Some users in Sui community are having troubles using Sui Wallet staking function, so here’s a guideline on how to work with that 
1. Make sure you are on the latest version of Sui Wallet (should be 23.1.26.226 // 28.01.2023)
2. Change the language of your Chrome browser to English (and delete other languages)
If you have done this, you can start interacting with Sui Wallet and delegate your tokens 
Don’t forget to faucet via Sui discord to get some test tokens.
