During the pointing, if the signal level bar graph is active but the % quality does not change, it means either the satellite dish is misaligned or the parameters (frequency, Pol, SR, or even FEC) of the transponder in the DVB-S2 terminal are incorrect.
(Same if using an external pointer for antenna adjustment)

For example, the correct parameters via HotBird 13°E (= Arte HD in clear) on a DVB-S2 receiver or on a pointer, it doesn’t matter:

If now searching for the Eutelsat 5WA 5°W satellite (formerly Atlantic-Bird 3) using "France 2 HD" in clear, the prior Fransat configuration is as follows:

Another example is Astra 19°E, channel I-télé in clear (from the TNTsat or Canalsat package):

In summary, ensure that the useful parameters are correctly stored in the decoder and correspond to those used on the satellite, knowing that some modulation data has been modified since April 2016 with the transition to all MPEG-4.
Sometimes we don't have our head on straight, and it's good to have a reminder like this question and the answer you provided.
