Why this rule existsrationale
The message flow has to hold the opt-in location, the consent wording, and a reference to the evidence, which does not fit in a sentence. The 2049-character ceiling is tighter than the description's, so a thorough flow can be truncated on submission without warning.
How to fix itremediation
Describe where and how consent is collected, including the exact disclosure wording shown to the consumer.
