Thank you for your message. We're actually in the process of closing our guest app unfortunately, as it doesn't currently provide the best user experience that we know it can do for our members. We are currently developing an exciting new planning app that will be a much better
experience for our members so keep an eye out for this in the coming months.
This does mean we are in the process of taking off the ability to set up a wedding via the guest app on the site or via the guest app itself at present, and we have also removed it from iTunes/Google Play stores too.
I hope this doesn't disappoint you too much. If you have any other queries please don't hesitate to ask.
