I'm having trouble reproducing this issue on any version of Orion iOS. I did some research and found that this seems to be a Notion error related to specific types of embeds, primarily embedded tweets. Sources:
I attempted to create a test notion page with an embedded tweet, but still am not having luck reproducing.
I'll look some more but without an ability to reproduce the bug, I'm not sure how to fix it. If there are any other settings I should try (extensions installed and active? unique settings, such as User Agent overrides?), let me know and I'll give them a shot.
Best,
