Ben here with the Webflow Customer Support Team!
Thanks so much for reporting this issue! An internal monitoring tool was implemented incorrectly. This incorrect implementation caused an error in the custom password page loading causing it to fall back to the default webflow password page.
This combined with it happening as we led into a weekend led to a longer wait time than normal to resolve issues like this.
This should now be fixed and should be working as expected. If you’re still experiencing any problems with the password page, please let me know and I’ll do my best to assist you.
