Zoho Assist "Agree and Download" Button "Greyed Out" ("Light Blued" Out)

Anyone else having issue where support clients are unable to click "Agree and Download" to access the client so that we can provide remote support?  This is for "on demand" support via accessing the support page and entering the support key and name.  This is not in any relation to "unattended access".

The button perpetually stays "Light blue" (see screenshot) and doesn't turn the normal "Dark blue" when it is ready to click/download the client "installer" EXE file.

*If it matters, we are using a custom/branded domain support page.  It has worked flawlessly for "years" up until today, so I don't think it is any kind of "setup issue" in relation to the branded settings since no changes were done over the weekend, but rather an issue on the Zoho server side.
