📘 Part of: #2435

Fixes #2443

Available Plans

To test

• CI must be 🟢
• Make sure you enabled winback FF
• Use a real device with a sandbox account
• Use a Plus/Patron account or a free account and purchase a Plan
• Got to your account, Cancel Subscription
• Tap on Looking for a different Plan
• ✅ Confirm you should see the list of plan. Your current plan should be selected
• Tapping on the same plan shouldn't do anything
• Tap on a different plan you should see the IAP panel prompted
• You can try to purchase and change plan with a sandbox account

Important:
The rows with Indaco theme are not properly displayed. We will address this in a new PR.

Checklist

• I have considered if this change warrants user-facing release notes and have added them to CHANGELOG.md if necessary.
• I have considered adding unit tests for my changes.
• I have updated (or requested that someone edit) the spreadsheet to reflect any new or changed analytics.

Great work!
Tested this with a brand new account and then purchased Plus monthly with a Sandbox account.
I was then able to upgrade to Plus Yearly, and from Plush Yearly to Patron monthly using the screen.
