We analyze the final release of the Planck satellite data to constrain thegravitational lensing potential in a model-independent manner. The amount oflensing determined from the smoothing of the acoustic peaks in the temperatureand polarization power spectra is 2$\sigma$ too high when compared with themeasurements using the lensing reconstruction and 2.8$\sigma$ too high whencompared with $\Lambda$CDM expectation based on the "unlensed" portion of thetemperature and polarization power spectra. The largest change from theprevious data release is the $\Lambda$CDM expectation, driven by improvedconstraints to the optical depth to reionization. The anomaly still isinconsistent with actual gravitational lensing, given that the lensingreconstruction constraints are discrepant independent of the model. Within thecontext of $\Lambda$CDM, improvements in its parameter constraints from lensingreconstruction bring this tension to 2.1$\sigma$ and from further adding baryonacoustic oscillation and Pantheon supernova data to a marginally higher2.2$\sigma$. Once these other measurements are included, marginalizing thislensing-like anomaly cannot substantially resolve tensions with low-redshiftmeasurements of $H_0$ and $S_8$ in $\Lambda$CDM, $\Lambda$CDM+$N_\mathrm{eff}$or $\Lambda$CDM+$\sum m_\nu$; furthermore the artificial strengthening ofconstraints on $\sum m_\nu$ is less than 20%.
