Healing potion update issue

Hello,
I have a critical Season 11 bug with the Alchemist.
The “Upgrade Healing Potion” category is completely missing from the Alchemist menu on my seasonal character.
I only see:
• Transmutation
• Craft Elixirs
• Craft Incense
There is no “Upgrade Healing Potion” tab at all, so I cannot upgrade my Healing Potion to Potent (70).
My character is level 70+, and this feature should be available.
I have already tried:
• Restarting the game
• Changing towns
• Switching World Tiers
• Switching Realms
• Teleporting to PvP zones
• Creating a new seasonal character
• Opening the Alchemist on another character
• Reinstalling the game
Nothing helped.
This appears to be a server-side data corruption issue, as confirmed by other players.
Please refresh or repair the Alchemist recipe data for my seasonal character so the “Upgrade Healing Potion” option appears again.
Thank you.

Alchemist does not improves potions after level 10 and later in the new season - PC General Discussion - Diablo IV Forums

there is no need to upgrade them anymore
