The above posts are correct. This is mostly implemented in order to save storage space and the associated costs. We have considered subscriptions which would, among many other things, enable the storage of more PMs. This would allow us to offset costs while ensuring we provide an improved experience to the user. At this time, however, we have not utilized those.
I will look at what can be done to alleviate this issue and see if a solution exists that would be feasible.
Thank you again for your feedback.
