It had been a while since i last remembered it, but i knew the reason was stupid. So, I had written reasons in italic. But, I guess that was up for open interpretation and that included questionable stuff.
Play Store has strict rules for apps with user generated content. You have to provide ways to block and report users/content to stay on the play store. Glider didn't provide a way to automatically report things by the user as hacker news doesn't provide one. So, google suspended it. Here's the github issue if you are interested: https://github.com/Mosc/Glider/issues/83
I kept on seeing that so frequently it became annoying. Later, I discovered it stopped when I started to use cloudflare dns with their playstore app. So, I think it must be rate limiting from lemmy.ml itself or some weird dns issue from my service provider.
If you are using hacker news on mobile. I would recommend Glider. It's a smooth hacker news client. Unfortunately, the dev had his app removed from the play store for reasons but you can access it from its github or fdroid.
Not much. Just that lemmy[.]world instance was hacked
