If you have over 30 or so accounts on your watchlist many won't load balances on a couple of chains.
For me they never showed on chain 0 and 1. Refreshing wouldn't help either.
Removing and readding an account would display all balances on all chains.
Now that I have cleaned house and back down to 20ish accounts I'm watching it loads fine every time on all chains again - same for refreshing, it also just werks now.
