Hi, thanks for reporting this bug. My phone doesn't freeze, but the post caused the app to crash yeah. Uploading a build that fixes the problem now.
For anyone interested in dev stuff, this issue was caused by an infinite loop in the regex replace function in swift. A part of my comment processing code fixes a few markdown issues where people often place an image inline that should actually be a big regular image. I forgot a single character in the regex that in some very rare circumstances (like the post you mentioned) caused the matcher to create another string that also matched, which is then replaced again, and again and again and again. Regex is great.
