file share app: v 1.8.0

The issue you are facing:
since i upgraded to v 16 of nextcloud, my shared folders are broken for anonymous users.
when someone wants to upload a folder it does nothing. JS console says this:
OCA.Files.Semaphore is not a constructor in file-upload.js :564:19

it worked perfectly well before the upgrade.
now i can only change files of shared “publicly open” folders, with the addition of a collaborator account.

also i cannot find a github folder dedicated to the Files app, otherwise i would have reported some stuff there.
there is no easy multi selection of files with shift + click or ctrl+clcik, which is astounding for a file browsing app.
