Hey there,
I know it is weekend, but I wanted to post this now before I forget this until monday.
Please be aware that the following refers to the mobile view of the page only. On desktop everything is working fine.
I use the quick registration module on my startpage and you can see, it works fine on mobile. But if you go on the link 'community' without being logged in, the component login and registration forms show and are not displayed correctly. In my case you can see that the recaptchas lays on the registration button and the PLZ field can not be reached.
I have a webview app and people getting there and complain about not being able to register on the site.
