Lensing-like tensions in the Planck legacy release
  We analyze the final release of the Planck satellite data to constrain the
gravitational lensing potential in a model-independent manner. The amount of
lensing determined from the smoothing of the acoustic peaks in the temperature
and polarization power spectra is 2$\sigma$ too high when compared with the
measurements using the lensing reconstruction and 2.8$\sigma$ too high when
compared with $\Lambda$CDM expectation based on the "unlensed" portion of the
temperature and polarization power spectra. The largest change from the
previous data release is the $\Lambda$CDM expectation, driven by improved
constraints to the optical depth to reionization. The anomaly still is
inconsistent with actual gravitational lensing, given that the lensing
reconstruction constraints are discrepant independent of the model. Within the
context of $\Lambda$CDM, improvements in its parameter constraints from lensing
reconstruction bring this tension to 2.1$\sigma$ and from further adding baryon
acoustic oscillation and Pantheon supernova data to a marginally higher
2.2$\sigma$. Once these other measurements are included, marginalizing this
lensing-like anomaly cannot substantially resolve tensions with low-redshift
measurements of $H_0$ and $S_8$ in $\Lambda$CDM, $\Lambda$CDM+$N_\mathrm{eff}$
or $\Lambda$CDM+$\sum m_\nu$; furthermore the artificial strengthening of
constraints on $\sum m_\nu$ is less than 20%.
