Question: After installing v2.1.5 of the module on M2.2.6, we cannot save product http://prntscr.com/llwor2
Could you please check if Catalog Price Scope config is Store view? (Configuration -> Catalog -> Catalog -> Price ->Catalog Price Scope )
FYI, it's the configuration to enable our extension on Backend. Thus, if you keep Catalog Price Scope config as Website or Global, it means that our extension is enabled in code but not on Backend, the issue will appear.
