I'm running into issues with SAGA processing algorithms in QGIS 3.18. QGIS tells me that SAGA 7.8.2 isn't supported, but doesn't tell me which versions are.
I've seen a suggestion that 2.3.x is officially supported, but how do I make QGIS aware of the version I've installed? I've tried downloading and installing SAGA 2.3.1, but QGIS still tells me I'm using the unsupported 7.8.2.
Uninstalling all versions of SAGA and then QGIS, followed by reinstalling QGIS 3.18 did the trick - it installed SAGA 2.3.2 linked to QGIS.
