There are many horror stories on this forum about Photos.
there sure are - because that is the only reason people come here - like a hospital emergency - not the place to judge the general health of a population
Photos works extremely well and if you want to solve your specific issues then it can be done but you have to be intelligent about it and post revelant details and questions, not off the wall crazy things like you are
again you can not migrate back but you can export and go back or go to any other program like LightRoom or others
And you probably can resolve yoru Photos issues if you want to - but the wayyou are going about it will ntoresolve anything
