    Hi @josephace135, thanks for making this contribution.

    I was able to replicate the above error. The app crashes when loading a post that has a special character before the title's text. The developers are aware of this thanks to you, and should have it fixed before the next version release.

    1. The post title contains sufficient information. Although, at first I wondered if the crash occurred whenever a special character was in the title, regardless of it's position in the title sentence.
    2. The expected and actual behaviors were properly explained as well
    3. The steps you provided were easy to follow. I had to add "design" to my initially selected communities, cause the others lacked posts with titles that started with special characters.
    4. I see you took the corrections on how to report a logcat and the important lines to include. The error here Caused by: java.lang.NullPointerException: lock == nullwas caused by the application's inability to access an object before it has been created, at least that's what this exception means. This could have been as a result of the exception encountered in this line java.lang.ExceptionInInitializerError You get this error whenever something goes wrong in the static initializer block. The special character obviously messed some code up, that the PO would have to look into.
    5. No proposed fix, still a great report.

    Thanks again for the contribution, it is a great find. I look forward to your next contribution,
