TL;DR
The learning phase is when Meta's algorithm is figuring out the best way to deliver your ads. It starts when you create a new ad set or make significant edits. During learning, performance is unstable and CPA is typically higher. The phase ends when your ad set accumulates approximately 50 optimisation events (conversions) within 7 days. To exit faster: set a sufficient budget (daily budget should be at least 10x your expected CPA), avoid frequent edits, consolidate ad sets, and do not use overly narrow audiences. Ad sets stuck in 'Learning Limited' are not getting enough conversions — broaden targeting or lower the optimisation event threshold.
