V. 0.18 disables CAPTCHA support, which we're not willing to do at this time, as there are a lot of bots on the platform. It's supposed to be re-instated in 0.18.1, so we're probably going to wait for that.
From what we understand, it should be possible to simply bypass the warning that Jerboa sends, and use the instance as normal - let us know if that's not the case.
Also, the instance can be installed as a PWA through Chrome on Android phones - I've found that to be a good experience overall.
