The official list of exactly which edits reset the learning phase, straight from Meta, which explains why a campaign that looked fine yesterday suddenly stops converting after a routine tweak.

- Batching multiple edits together triggers only one reset instead of several
- Pausing an ad set for more than 7 days also resets it on reactivation
