@PhilipDAth Thanks for your contribution on this, Can't find any way to download the sponsored splash page to customize it, could you please elaborate on how to do that from the dashboard
As per Meraki documentation you need to create a specific domain for the IT people to use it to grant access so the guest cant use any email from the main domain (which is not really efficient way and acceptable for the management)
Quote from the documentation of the sponsored guest access "Please note that any user with an email from the specified domain will be able to grant access to the guests if the guests select that email. If an organization needs only specific emails, like the emails of the IT administrators, to grant access to guest users, the IT administrator team has to have emails on a different domain than the other employees of the organization and must specify that domain as the "sponsor email domain", a domain with only those few email addresses on. For example, if the specified domain is meraki.net, any employee with a username@meraki.net email will be able to sponsor the guests. If the administrators want only specific emails to have the authority, then the specified domain has to be a different domain for example "@merakiguestsponsor.net" with only a few emails on that domain like username@merakiguestsponsor.net that can be specified by guests to grant access to them. "
Many thanks in advance
