Bug Description

Instead of the formatted text, 2 documents randomly started displaying the 'The current version does not support this block' error message. Happens on both mobile and PC. So far, it’s only affecting documents.

Using AppFlowy Cloud Beta to sync data.

Case 1

On PC, the document is showing up correctly. On mobile, the first toggle is replaced by the error message. The second toggle appears, but some of the to-do items below it are gone.

Case 2

The document appears fine on mobile. But on PC, there’s the error message instead of data.

In both cases, attempts to edit the document either on mobile or on PC don’t transfer to the other device. Other documents, grids, boards and calendars are syncing correctly.

How to Reproduce

Unsure.

Case 1 block content:
{"type":"toggle_list","children":[{"type":"todo_list"},{"type":"todo_list"},{"type":"todo_list"},{"type":"todo_list"},{"type":"todo_list"},{"type":"todo_list","data":{"delta":[{"insert":"Avižos be gliuteno"}],"checked":false}}]}

{"type":"todo_list"}

Case 2 block content:
{"type":"bulleted_list"}

{"type":"bulleted_list","children":[{"type":""}]}

{"type":"bulleted_list"}

Expected Behavior

Display the entered data; sync and display document changes.

Operating System

Android 14 and Linux (Feren OS) focal 20.04

AppFlowy Version(s)

0.5.4 on both systems
