Hey,

i’m not sure how much of a help a “me too” in a user support forums is if there was already a bugreport done previously. :confused:

But if i’m clicking on the link posted by @anon30676603 above i can find the following statement:

This is basically a known “issue” - some zip tools don’t support all specifications of of zip.
Not much we can do → close

If i’m understanding this correctly there won’t be a possible solution.

ZIP folder then share is my solution.
