Question Web Presence Builder doesn't like MS-EDGE

[Piet999]

Hello

For a client, I have to realize several homepages with a builder, so he can change things by himself.

First homepage is ok and works.
Second homepage (other layout, template) doesn't work correctly and welcomes visitors with the message to update to an actual browser But it is - the newest MS-EDGE.

How to fix or in minimum suppress this message?

(German Version of Web Presence Builder 18.0.29)

Thanks for reading and please - I accept each hint.
