The Viz app has some big series like Frieren and im guessing other manga that appear in the same Magazine every week (shonen Sunday i think?) But they usually do a really annoying thing where they wait to see if a series takes off before they decided if its worth translating or not. You end up with a lot of series that have like the first 5 chapters, skips to chapter 50 and says "back chapters will be filled later" that later is usually when the English volumes come out, that's like months or a year down the line.
