nRF52 ACK with payload in static payload mode

That sounds like an error in the documentation. The first version of the library went up to 32 bytes only, similar to the original ESB protocol, but I added a quasi ESB mode with an extended length field that could go further.

Theoretically you should be able to go up to 253 bytes on the nRF52, I don't know if you tried that?

Ah ok this is a little bit confusing. One further question: In the documentation it is written that the dynamic payload is limited to 32 Bytes. But for me it is workinig up to 252 Bytes with dynamic payloads. Is it correct?

This is probably not brilliantly documented, but you have to use the UESB_PROTOCOL_ESB_DPL mode to be able to send ACK payloads.

UESB_PROTOCOL_ESB_DPL essentially allows the following three features:

Dynamic payload length
ACK payload
Dynamic ACK (being able to send packets without ACK on a packet to packet basis)
