A new (annoying, unnecessary) protection against Excel links ? (topic closed) [solved]

Hello,

I have an excel sheet for my sales with a link to the Numista page and today links don't work anymore.

Example of Excel links: 

which works if you put it in the address line but which gives the result:

Other example which doesn't work anymore in excel: 

Is it possible to allow again links from Excel ?

It works again this evening.

Thanks
