Service tab Sept 2 and accepting friends

I think I am talking about something new, but you will all let me know. I had an unprecedented amount of people to accept as friends today, something like 15, and now after I accepted them all as I am working to 500, my services tab is blank. Anyone else?

Yep, happened to me today too!

The service tab goes blank at times, seemingly at random. I haven't figured out a pattern to what makes it go blank nor to what makes it come back. I've managed to get it back by closing the game (full close) and restarting it, but it doesn't work every time. I've had it come back after visiting a friend, but, again, it doesn't work every time. And I can never tell what triggers it to go blank. Sometimes I can enter just 3 friend codes while other times I can enter 50. Even the time of day doesn't seem to matter.

When it goes blank, just do something else for awhile, and then check it again later. It generally comes back again.
