ASUS RT-AC86U Firmware version 3.0.0.4.386_51967 not installing

[MakeItEasy]

Hello

I have fw 3.0.0.4.386_51955 and I see there is a 3.0.0.4.386_51967 available (https://www.asus.com/networking-iot...rs/rt-ac86u/helpdesk_bios?model2Name=RT-AC86U) but I'm unable to install through the UI: I have a page "firwmare is downloading" and nothing happens next.
Don't know why, this is the first time it hasn't worked.
Is it worth installing it ?

I tried again after reboot and it worked this time.
