A user reports that the app brings up a black screen and becomes unresponsive (shows “Application Not Responding (ANR)” error dialog) when loading large posts. The post does eventually load in the editor after choosing to wait.

In the reported case, the word count for the post is about 20,500 words (400 kb of content) and has a large amount of HTML. I tested with a post that has about 30,000 words (400 kb of content) and reproduced the black screen briefly, but no ANR error dialog. It's possible that the ANR is related to Aztec processing the HTML in the post, as well as the text content.

We should keep an eye on how Gutenberg performs with posts like this.
