I can sometimes see the Freerse page flashing in load, like it's preparing a feed, and then it goes blank.

You can help with the test. Log out of your account. Then re-open the App, register a new account, and follow some users. See if there is post data in the feed. Is it a relay problem? 🤔
Hmm... Yes, now I see a feed.
But I saw one for a while, with the normal account, too. Let me use it for a while.
When it loads, I see this:

This page is the loading page for the feed. The feed will take about 10 seconds to read. The default relay is now used. Can the Feed read the data?

Only with the new npub
Yes, it may be the relay's fault. You have been using it for a while after our updated version. The feeds are working properly. Your new npub uses the 21 relays we recommended. The relay you are using now is the one you selected. Have you encountered the problem of no data in the feed in other clients?
