I downloaded a 200 MB app over Cellular data today. Then I tried another 300 MB app, with no warnings whatsoever, and the download completed successfully. Final I tried a 1.2 GB download which failed with the popup warning message.
I understand that App Slicing has appeared since iOS 9. The actual download size is different from the indicated size. But after downloading, I checked in Setting app → General → → iPhone Storage, and the two apps are over 150 MB(198 MB and 211 MB). And they are new download not updates.
Is the size displayed incorrectly or has the upper cap for downloading new apps over Cellular data changed?
PS:I downloaded that two app before but uninstalled it. Another assumption is that the downloaded content is actually less than 150 MB but there is a process of decompression?
