This is not a complaint nor an actual problem for me, I just want to make sure that everything is ok. I am getting a lot of updates, today for example I got 3 or 4. Is that the case for everyone else ?
They team is working hard in Denver on the App Center sprint. The updates are likely part of that.
This is not an answer to your question, just an affirmation that today I also got 4 updates. I guess that this was normal.
