Lucas	d46b8bf79a	Remove translations with duplicate English strings (#980 ) Linter no longer complains about this, this causes confusion on how much of monerujo is translated, this breaks translation language fallback (e.g. get translations from pt if pt-br doesn't have them) Includes mixed strings unfortunately, mostly found in the help strings, where there were a few that have english in the middle, unfortunately... having them would mean they would likely be skipped over, there's no way I know to fix this, a lot of these though need overall maintenance, and it's better to make the job easier for the translators than to keep a potentially confusing/breaking translation	2024-12-07 10:41:03 +01:00
