Great game but one thing.. – Cow Evolution: Evolve Animals Review

So I had an iPhone 6 and I had played this game so much , at least for 5 months and I had gotten so far. I recently got an iPhone 11 and re downloaded all my games including this one, and when I loaded it up all my progress was completely gone, and under the supports of the app it says it supports Game Center, so all my progress should have saved but it didn’t, and it’s really disappointing because this game was so much fun.
