They’re letting you choose a custom address as soon as you reach 1M sats in onchain transactions.

No way?! How are you able to track your total spend via WOS?
It’s not total spends, it’s just onchain transactions — gotta send or receive 1M sats onchain — there’s a bar showing how many more sats you should transact before you can customize the address. 
Man, I am so perplexed.
Where are you finding that Lightning Address screen in the WOS app?
I see no such way to get there.
