The bad is eval file is not like book, engine plays slow only using eval file.

I liked It. It has an interesting game style.

Is it normal it makes a2-a3?

See pm

In a controversial move SF Dev has "merged" SF Dev NNUE with regular SF Development...engine has only the option for "part time" NNUE search....is now a "Hybrid Engine Concept".......

I did not like that. Nnue lose identity.
The New stock, plays different.

if anyone have the sfnnue for andriod send me the link

I have downloaded the latest Stockfish NNUE from https://abrok.eu/stockfish/
Am I supposed to get "info string NNUE nn.bin found & loaded" when I perform these commands:
setoption name Use NNUE value true
setoption name evalfile value nn.nnue
isready
ucinewgame

Am I doing something wrong or forgetting other steps?

Try indicate full path in parameters.

Or new versions are not sending this message anymore.

The engine parameter contains the name, copy and rename the network, without the eval folder

Changes:

Merged the official Stockfish master branch. (27b593a)
convert_bin Clamped score between -32,000 to 32,000. Thank you, tttak!
convert_bin Excluded invalid fens. Thank you, tttak!
convert_bin Excluded invlaid moves. Thank you, tttak!
gensfen Fixed a bug that the random seed is always constant. (#68)
gensfen Fixed a bug that the training data generator does not use EGTB. Thank you, linox! (#67)
gensfen Fixed a bug that the training data generator crashes when eval_limit is high. (#77)
gensfen detect_draw_by_consecutive_low_score option is added. If detect_draw_by_consecutive_low_score is set to 1, the training data generator adjudicates game to a draw if the last 4 moves of each engine has a score of zero starting at ply 80. The default value is 0. Thank you, linox.
gensfen detect_draw_by_insufficient_mating_material option is added. If detect_draw_by_insufficient_mating_material is set to 1, the training data generator terminates the game early and not wait for 2-fold repetition in KvK, KBvK/KvKB or KNvK/KvKN and KBvKB (same bishop color). The default value is 0. Thank you, linox.
gensfen Renamed use_draw_in_training_data_generation option to write_out_draw_game_in_training_data_generation. The old option name is still available.
learn Renamed use_draw_in_training to use_draw_games_in_training. The old option name is still available.
learn Renamed use_draw_in_validation to use_draw_games_in_validation. The old option name is still available.
learn Renamed use_hash_in_training to skip_duplicated_positions_in_training. The old option name is still available.
The network parameter file is not included in this release. Please download the strongest network parameter file on fishtest (https://tests.stockfishchess.org/nns). If there are questions, ask in the Stockfish unofficial Discord server (https://discord.gg/ZzJwPv3) at first.

So you don't create an "Eval" folder and copy the nn.bin?
How do you install it?

Best regards!

In Fritz and the Arena GUI do I have to write the whole path where the file is located or put it in the folder that is the engine and just write its name?

I'm sorry about my bad English.
