I want to know the answer to the following question:
What are the two most common reasons one Grand Lodge will withhold recognition from another?
All the background I'm provided with is that "When two Grand Lodges recognise and are in Masonic communication with each other, they are said to be in amity, and the brethren of each may visit each other's Lodges and interact Masonically.". Is that enough to answer the question?
Answer: no
