This is happening exclusively with this plugin, all the rest of them update correctly. We have purchased this addon and succesfully added the Key. The main "ATUM Inventory Management for WooCommerce" updates fine.
Thanks for letting us know about this.
We are already aware of this issue and we're investigating it just now.
It should be working fine now. Please try again and let us know if it works for you.
Salva It worked now, thank you!
