EDIT : Apologies for our previous reply. We made a mistake and linked the limitations from our other reflections tool instead. The update for this tool to improve support for Unity 2019 + LWRP will become available NEXT week since the upcoming update will mark version 2.8, a huge UI update and many new improvements as we approach the release of version 3 (~September). However, and again, the limitations are similar. Post Process Stack v2 will be fully supported without errors after the update, but it makes the reflections more expensive to compute. The reflections are not compatible with Motion Vector based effects, as these are not correctly rendered on the reflection itself. Besides some limits on the preview mode (Scene View) and lack of support for multiple cameras and the static background + dynamic objects mix shader, PIDI Planar Reflections on LWRP is basically the same asset and has the same features and support. We recommend that, if you can wait for the update (its release will be announced here) you wait for it as it will be more sure that all the features you need have been thoroughly tested for 2019.1 and 2019.2 Again, apologies for our previous information, we hope this helps!
