@noodlemaz Not per app but FWIW, I was told before: "Automatic #translation is available but it's up to server admins to switch it on. It's a paid API service from open source LibreTranslate.com - many servers lack enough funds."
N.B. ArgosTranslate has to support the relevant language(s): q.v. https://github.com/argosopentech/argos-translate/discussions/91?sort=new
#DeepL is used on some servers (dunno how), but it has limited languages (e.g. no Welsh, unlike Google Translate, Bing, Facebook, Twitter...).
