Upload of Apple redemption codes shows error "Value was either too large or too small for an Int32"
I am wondering if anybody of you guys have experience on working with redemption codes for custom iOS applications?
I have the situation that I just download the generated redemption codes from the Apple Business Manager portal, but everytime I try to upload it it fails with the message "Value was either too large or too small for an Int32".
I figured already out that if I change a bit in the excel the upload works but the licenses are not shown in WS1 and the app cannot be installed.
The App itself and the codes are working fine if I try to install it manually.
So maybe some of you have seen an issue like that before?
I already opened a case regarding that but until now it seems it is more an issue on apple site and not on WS1.
