Any ideas in layman's language what this means? It occurs from time to time in MacOS Wallet. Will this be a permanent error for that wallet address? What caused it? Is there historic data missing? What effects does it have? It's not a UX friendly message ))

Are you trying to read old transactions?

The wallet would be as it always has a history, I'm just using Wallet as any normal user. When I scroll back sometimes all the history is there, sometimes not, like right now, it only goes back a month, is this the error? But then sometimes it must be working? The error shows up quite often, maybe once a day or more in normal usage.

I quit the wallet, started it again, and all history is there without any error message. Whatever causes this error is not UX friendly and would cause users concern.

I totally agree with you. But that's how the web wallet is implemented right now.

I'm sorry, but this chat is only for development questions.
