I can't get it to work for me. I did the add to home screen but it just opens up in a chrome tab for me.
Edit: Turns out I had to disable AdGuard temporarily and then kbin's install app banner popped up and that worked. Only issue is it doesn't respect my device's do-not-rotate setting, but I know somebody has added that as an issue so hopefully will be fixed pulled in to the codebase soon.
Well that's an entire hassle and seems far from ideal, lol. I have a mastodon account I never use, but for now I'm just gonna stick to kbin and follow whatever lemmy folks or whatever I want from here.
