I use to had the same issue, but I always thought it was because I cleaned the explorer cache. But actually now I 'm really loving the steemx.org site because also has the translation function inside the page, so you can choose what to translate and onto what language.
I get a bit tired of all those sites and adding all the keys. I will see what I will use in the future. And if I can't translate I let it be.
Yes, that's the problem with keys 😞 and I didn't find an app for Steem, is there anyone?
As far as I know there are no apps. I which there was one like in the old days. I liked Partiko a lot.
Yeah, it would be great. Maybe soon the steemx team will launch their app, I saw one publication about that.
