But…, The Arrow Of Time “Paradox”?

For many decades we have been told that in the microcosm time is symmetric and can run forwards or backwards. Feynman famously interpreted the positron as an electron moving backwards in time.

Here is the standard argument that was dominant in my lifetime:

“Physical processes at the microscopic level are believed to be either entirely or mostly time-symmetric: if the direction of time were to reverse, the theoretical statements that describe them would remain true. Yet at the macroscopic level it often appears that this is not the case: there is an obvious direction (or flow) of time.”

So are we now admitting that there is an arrow of time that runs one way at any scale (with exceedingly short violations possible so long as CPT is preserved)? Please clarify this succinctly and directly.
