Hi varange
I've just tried the same as you and worked correctly for me (both, SKU and title worked). Please, make sure you have all your plugins up to date.
the Stocktake Add-On. Any timeline on completion?
The Stock takes will come first as part of the ATUM mobile APP that should be released in mid 2021.
Later, we'll develop an ATUM Stock Takes WP add-on but don't have an ETA for this (the development has not started yet).
I'd also like to see a Premium version of ATUM with extra support options.
What do you mean? We already offer free support for ATUM free plugin and premium support for our premium add-ons' users.
Best Regards,
Salva.
