Unable to change manga reading status [Solved]

[Mek]

Can change the status from Reading to Completed but when refreshing the page it shows as Reading again and only Ijiranaide, Nagatoro-san seems to be affected of this. No issue doing same for Senpai ga Uzai Kouhai no Hanashi as an example.

Using Chrome Version 127.0.6533.72:

• Incognito mode
• Logout
• From another device
• From phone connected to mobile broadband (not wifi)
• I get 200 OK for the follow and status POST

Found another thread where the solution was to set status to None first and the Completed which also worked for me!
