Blank study screen

AnkiMobile (iPhone/iPad) Help
1

i have the same problem ,but it only hanppened on my mobile devices .

  1. Core Problem Description

Symptom: After tapping “Learn” or “Review” for any deck, the main card display area is completely white/blank. No card content is rendered.

Key Clue 1: Browse mode works perfectly. I can see all cards and preview their content normally. This confirms card data is intact and synced.

Key Clue 2: The study status bar at the bottom (showing card counts) sometimes gets stuck and does not update when switching decks.

Scope: This issue occurs simultaneously with identical symptoms on both my iPad and iPhone.

  1. Exhaustive Troubleshooting Performed (All Failed)
    I have tried all standard fixes, including but not limited to:

Performing a “Full Sync” within AnkiMobile.

Logging out, deleting the app, rebooting the device, reinstalling the app, logging back in, and doing a full sync.

Creating and logging into a brand-new AnkiWeb test account – the problem persisted.

Not logging into any account, creating a new local deck with simple text cards – the screen remained white when attempting to study.

Confirmed that Anki data is NOT synced via iCloud between my iPad and iPhone.

Verified correct system Date, Time, and Region settings.

  1. Device & Software Information

Affected Devices: iPad (Model: 2021）, iPhone (Model: 14)

iOS Version: iPad (17.7), iPhone (18.6.2)

AnkiMobile App Version: 25.09

AnkiWeb Account: a790760239@126.com

  1. Request
    Given that the issue is consistently reproducible across two independent devices and all common factors (account, data, basic settings) have been ruled out, this strongly suggests a compatibility bug or rendering engine failure specific to AnkiMobile and my current iOS environment.
    I kindly request the technical team to investigate this issue and provide any possible workarounds or a fix timeline. I am ready to provide further logs or testing information if needed.

I split you off into your own thread. It seems unlikely that you’re having the same issue as that other user, since their issue was deck/note/note type-specific.

But if you were – then you would need to start by trying everything suggested for them.
