This possible bug report is similar to the bug in Answer has text now that was deemed not-reproducible. I can reproduce something similar with more recent app & Android versions.
App Version: 1.0.34 (original report; is still present in 1.0.38, 1.0.42, 1.0.58)
Android Version: 4.4 (up to 4.4.4)
Device: Motorola Droid Maxx
In the examples below, you can see some blank answer bodies. These are on different sites, and represent answers with both edited and non-edited text. In the first example, I clicked on the top answer tab to get to the answers, and in the second example I clicked on the bottom "View n Answers" button. (Trying to be a good little tester!)
Because I've seen this blank-answer-body intermittently over the past couple weeks (before the May 7 update), my process to test was just to go to the first site I frequent and then systematically click through the question list until I found a question with answers in which at least one answer was blank. For all three sites shown below, it was within the first 5 or 7 questions sorted by newest. Please note that I have seen many questions with several answers, none of which were blank. It is truly intermittent.
Example blank answer body at Workplace.SE:
Example blank answer body at Programmers.SE:
Example blank answer body at UX.SE:
And now here's the kicker, which makes me think this is some sort of content-loading latency issue rather than a rendering issue:
I returned to the left-side menu, selected the User Experience site, picked the same question as above, and then clicked the top answer tab to view answers again, and lo and behold the text is there:
I then went back to the other questions with blank answers, shown above, and the answer bodies were no longer blank.
I am happy to go through more tests/paths and do screenshots if it is helpful.
The same bug also appears in question bodies.
