Incorrect zero balances at times

[BrightonDube]

Describe the bug
There are two bugs: 1. Every now and then I open my wallet and it shows zero balances for all coins and tokens even though the actuall balance is not zero.
2: While sending Eth or tokens, when I click on gas settings, the wheel just spins non-stop until I refresh and this happens so often and it forces me to filling in the transaction form. I need to send tokens to hundreds of addresses at a time and having to restart the process is really annoying if i have to do it every other transaction.

Also experience this when switching from one account to another. It might be better if we simply show -- ETH rather than 0.00 ETH until it loads. Or even a mini spinwheel where the balance typically is.

[dpazdan]

we could improve the UI by having a "last updated" date/time visible, so when you open the extension, it has that info avail, and displays your balances from the last time it pulled. Then if it updates successfully, it changes to "updated just now"

I am still seeing the zero balance issue. It also manifests by preventing you from signing the current transaction. Example:

The workaround is to reject the transaction and try again.

@danjm is this something that's helped by caching balances?

Closing this due to lack of activity and addition to cached balances in #5843. If this is still an issue in the latest version please open a new issue.
