Creating a Stamp

As Acrobat continues to deteriorate in terms of ease of use and instead overwhelm us with AI suggestions that use resources and are not even helpful, I notice another of my often used features has gone.

I use to use the stamp tool to stamp invoices as received, agreed and paid.  They would use the different colours that stamps can have, and put the relevant word inside, and the date. (dynamic)

However now these stamps have disappeared, and I can see no way to get them back.

Asking the auto-support just tells me I need to create images, which removes the whole idea of a dynamic tool… 

Anyone know where they’ve gone?

Thanks
