Have already tested the direct upload with all different Mathcad/Prime files in the private "PTC Community Refresh" board
https://community.ptc.com/t5/PTC-Community-Refresh/Mathcad-File-Types-Fix-is-HERE/td-p/547263/jump-to/first-unread-message
from two different Systems and was successful both times.
So I suppose we can say that this bug finally got fixed and we can continue attaching files like we were used to do before the migration.
Next step: Uploading/inserting picture by simple cut and paste (also as we were used to do before the migration) 😉
