Tried this, did not work for me!
Hi team so i just messaged a contact of mine they are aware of the issue and here is the board - status update - Webflow Status - Reports of Inability to Edit Number Input Fields in the Style Panel
Hi all - this issue has now been fully resolved. Weâre so sorry for the inconvenience and confusion this caused.
Thank you for your patience while we investigated and addressed the issue. If youâre still experiencing any unexpected behavior, please donât hesitate to let us know. Weâre here to help 
youâre not alone, me too 
I have the same problem right now
Same issue! Phew, thank goodness â I thought my system was malfunctioning and started uninstalling peripheral drivers, thinking they were causing some kind of conflict.
Still not functional.
For anyone still experiencing this, Webflow has reported itâs fixed- I would recommend you clear your browser cache and reload the designer to ensure you have all the current designer code.
