MPK Mini Plus. Transport not working

Hello. Anyone could advise where to look to make MPC Beats to read Transport messages from MPK, please?

Background:
- I am new to MPK/MPC
- On a 1st day of installing all software and configuring ... all worked well
- On a 2nd day ... MPC Beats stopped responding to "Transport" (play, stop, record etc). - All pads and keys are working fine, but transport is not.
- I tried Wizard, re-installing MPC Beats, resetting "Program 1" via MPK Editor, switching off and on the "Control" button in Preferences, even tried to use "Learn" function to manually assign transport buttons. - No luck.
- I see when I push a transport button then in MPC Beats UI (top right corner) an indicator lights up confirming it receives a CC, but it does not do anything.

Anyone?

To get transpsort back hold CTRL+SHIFT+L to open the MIDI learn panel and select Enable, Akai MPK Mini Plus should be in the menu next to it, if not use the drop down menu, now the transport functions will work.
