And this is not true.
One should distinguish what observer sees with his eyes and what he
calculates.
If A is on earth and B is moving towards the star and back then what A
sees:
1) on the way forward the processes of B are slowed due to doppler
effect on receding objects (red shift)
2) on the way backward the processes of B are fastend due to doppler
effect on approaching objects (blue shift)

what A calculates based on his understanding of simultanious with him
reality ( all the "there-now" dots that represent the current state of
the world even though the light has not passed from "there-now" yet to
see what actually is going on there)

1) B estimated time-flow is slower than A
2) B estimated time-flow is slower than A

If u still dont understand the difference between "actually see" and
"calculate/estimate to be happening there-now" then you should ask
yourself:
Is the Sun i see here right now and the Sun that is "there-now" the
same or not ? Does the Sun "there-now" exists at all or was it
probably blown or moved away by some aliens moments ago ? Is the
estimated "there-now" reality a reality at all or just a projection of
what the things are expected to be based on what info has reached me
from the past?
