I just switched from QGIS 2.8 to 3.4. On the fly projection does not appear to be working. None of the Google searches I do provide help. Looks like most folks want to turn OTF off, and it sounds like it is supposed to be on, but each time I add a layer it shows up in an unexpected place.
Problem with "On the Fly Projection" (OTF) in QGIS 3.4 when upgrading from QGIS version 2.8 [closed]

1In (QGIS 3) Project ~> Properties ~> CRS you can define the map canvas CRS. If the canvas has a defined CRS, then it will reproject the layers on-the-fly. If No projection is ticked on, then the map canvas has not a defined CRS and the layers will not be reprojected on-the-fly.– Gabriel De LucaFeb 4, 2020 at 21:11

There is no question here. It's formatted like a bug report, and the vast majority of users will attest that OTF projection works fine.– GabrielFeb 5, 2020 at 15:14

About the QGIS 2 On-The-Fly reprojection, in QGIS 3:
In QGIS 3, in Project ~> Properties ~> CRS, you can define the Coordinate Reference System (CRS) for the project map canvas.
If the canvas has a defined CRS, then QGIS will reproject the layers on-the-fly to that CRS before show them on the map.
If "No projection" is ticked on, then the project map canvas has not a defined CRS and the layers will not be reprojected on-the-fly. The layers will be shown on the map without reproject them to a common CRS.
