  We study here the phenomena of decayless kink oscillations in a system of
active region (AR) coronal loops. Using high resolution observations from two
different instruments, namely the Extreme Ultraviolet Imager (EUI) on board
Solar Orbiter and the Atmospheric Imaging Assembly (AIA) on board the Solar
Dynamics Observatory, we follow these AR loops for an hour each on three
consecutive days. Our results show significantly more resolved decayless waves
in the higher-resolution EUI data compared with the AIA data. Furthermore, the
same system of loops exhibits many of these decayless oscillations on Day-2,
while on Day-3, we detect very few oscillations and on Day-1, we find none at
all. Analysis of photospheric magnetic field data reveals that at most times,
these loops were rooted in sunspots, where supergranular flows are generally
absent. This suggests that supergranular flows, which are often invoked as
drivers of decayless waves, are not necessarily driving such oscillations in
our observations. Similarly, our findings also cast doubt on other possible
drivers of these waves, such as a transient driver or mode conversion of
longitudinal waves near the loop footpoints. In conclusion, through our
analysis we find that none of the commonly suspected sources proposed to drive
decayless oscillations in active region loops seems to be operating in this
event and hence, the search for that elusive wave driver needs to continue.
