Yesterday (30th September 2020) I extended my Substance Painter and Designer perpetual licenses to 09/2021. The purchase was successful and they almost immediately showed up on my licenses page.
This morning they were both still showing extended to 09/2021. Before I'd downloaded and authorized them I went onto the partnership page and clicked the sync with steam expecting it to auto-update my steam version of designer and painter.
Instead, it seems to have erased my upgraded licenses back to being expired.
Please help!
