The Google Play Store version crashed instantly on launch after flashing up the changelog (mentioning v0.0.35) but looking at app info it said version 0.0.33 so maybe the play store hadn’t rolled out the latest build. Installed the GitHub release apk instead and had no issues.
The 0.18.0 lemmy release is going official tomorrow, I’d assume lemmy instances will be quick enough to pick it up once available.
