Bug: Memoization feature cause problem

When I'm working with the app, for example, I may forget to connect to the internet, shut down VPN, change proxy settings or something like that and want to recheck the domain again, but it's not possible because of the memoization feature, and the status "offline" is still displayed. In such circumstances, I can't try again unless I reopen the app.
Hence, the memoization feature is not helpful here.
