I have subscribed to the Stream+ Bundle and have read many help articles, FAQs and forum posts, but I cannot seem to link my Prime account. I have disconnected my subscription from Google Play and been in touch with Amazon support twice, they are unable to help at this time. I just get the usual “existing prime members are ineligible for this promotion” error. When I spoke to the last help agent, they told me my membership must be handled by the 3rd party.
What is the trouble with the account linking? Can you help please?
