How it played out

Retrospective analysisNovember 4, 2026

The average rating declined by 0.83 stars following the update, driven by widespread user reports of login failures and broken navigation paths. The redesign, intended to improve account management, has instead introduced critical access barriers that prevent users from viewing data usage or managing subscriptions. Momentum is currently weakening as the update has significantly increased the volume of negative sentiment regarding core functionality.
