Billz,
I am currently reviewing the details for a Ford ESP myself. I believe on the Ford ESP site it states acknowledgement of the selected plan appears on the Lincoln app. I am a bit leery of putting money down on a plan, and the money/plan not being credited to my account.
Verification is important to me. I would call Lincoln Concierge, as well as the dealer you purchased the plan from to verify & show proof of enrollment.
I am very surprised that Lincoln Corporate does not send verification directly to the purchaser by means other then the Lincoln App. Makes it too easy for the plan writer to "forget" to submit the plan. Years ago, I witnessed this occur at a Lincoln dealer I worked at. I am sure the scam was entirely on the part of the general sales manager, and that the owner(s) were not aware of what he was doing.
