I am the administrator, it can't be an authorisation problem.

I therefore took a look at the network traffic and compared the behaviour in the old UI with the behaviour in the new one. Both GET requests are listed below, where you can already see the problem. I have anonymised the specific information with x.

GET https://desk.zoho.eu/support/xxxxxxxxxxxxxxxxx/connectzb?entityType=12&acceptJHTML=true&entityid=xxxxxxxxxxxxxxxxx&accountType=ZohoInvoice

OLD UI
GET https://desk.zoho.eu/support/xxxxxxxxxxxxxxxxx/connectzb?entityType=12&entityid=xxxxxxxxxxxxxxxxx&accountType=ZohoBooks&userdepid=xxxxxxxxxxxxxxxxx

As you can see, it tries to access ZohoInvoice, but this extension is not installed because we use Zoho Books. It is a pity that the old user interface still has to be used because of something like this.

Have you noticed such an error? I look forward to your responses.

Regards,

Sven
