Hello, I lost my Plants vs Zombies 2 progress on iPhone

Hello,

I lost my Plants vs Zombies 2 progress on iPhone.

My game restarted from zero even though my progress was previously saved with Game Center.

Important: I had completed all worlds in the game and made significant progress.

Device: iPhone

Login method: Game Center

Issue: Progress reset / started from zero

Please help me restore my fully completed progress linked to my Game Center account.

Thank you
