Migrate Max access before renewals split across devices

You’re the software engineer. Your team is in the room. Printed Oct 13, 2026.

The Max retirement must preserve access without extending the wrong entitlement.

Active subscribers need uninterrupted practice, while purchase records must remain authoritative across every surface.

Who you’d be doing this for

“My lesson worked on my phone this morning, then my tablet told me to subscribe again.”

Dalia Kirui · Daily Practice Learner

An active Max subscriber who uses premium access to keep a daily learning routine uninterrupted.

What is at stake

Active Max subscribers are receiving conflicting premium access across devices as renewal approaches. You must weigh uninterrupted practice against irreversible entitlement and billing mistakes.

Why it isn’t already fixed

Every obvious fix costs something else. That’s the part you’d have to decide.

  • continuous practice vs entitlement accuracy
  • renewal speed vs evidence review
  • store receipt authority vs backend consistency
  • revenue protection vs learner trust

Why Duolingo

Super subscribers depend on reliable premium access across the learning app as the tier ladder changes.

This is the setup. The work is inside.

Running it puts you in the room: the full situation and its constraints, stakeholders who push back in their own words, and the decisions that are yours to make. What you produce becomes a Day One Plan — work you can show someone instead of describing.
