I agree with you Steemit interface is making problems in loading from the last day in my experience.

Recently I opened some posts and loaded some user profile for the confirmation to set beneficiary but even with the correct username it showed the user does not exist. After several refreshes it worked.

So the problem is the one we've faced countless times before and is something that I believe requires server access to fix (i.e. somebody in the Steemit IT Team).

For this I am mentioning @steemitblog @steemcurator01 so that we can fix the problem and can have a smooth experience.
