When i start VO on android, i see the Guild Software logo. After that it crashes.
Updated today to 1.8.503, wasn't running for some months, but worked before.
I tried a fresh install including wiping existing data, with the same crash happening.

So, you're using one of these boards?

We'll take a look sometime soon.

Also, general, crashes and things are best suited to the Bugs forum. We don't check the platform-specific forums very often.

Yes that is correct. Will post crashes and such to the bugs forum next time. Feel free to move it there.
