mAP 2n - Hotspot HTML files vanish after reboot

I saved customized hotspot html files in the root. I noticed the files vanish after device reboot.
After research, it seems this is a “feature” of mAP.

Is there anyway to disable this feature?

When I put the html files under “flash” folder, the hotspot function does not work. I kept getting error 404 when opening the walled-garden.

Update your RouterOS to v6.30 and set up hotspot again, it should put all the files under /flash/ directory.
