They have not disappeared. They were moved to a better location. See College Weekend in the Events category.

You can still download Sermons, Events and Studio recordings. However, you must be in a specific category (a congregation in Sermons, or a particular event in Events e.g. Brotherhood Conferences, ACCFS Conferences, etc. or select the studio series you want in Studio, such as Breaking Bread) in order to get the download option, which is a "download from the cloud" icon. This also allows downloading multiple items at once.

Events can be downloaded. Just like with Sermons, you do need to be in a specific category (e.g. Brotherhood Conferences, ACCFS Conferences, etc.) in order to get the download option.

Download and attachment functionality has been restored for individual church website sermon pages.

We are aware that some users have been experiencing stream interruptions and have had our developers looking into this for many months. It has been a major challenge to isolate the exact problem, given the large number of variables with every church, device, internet connection, OS version, etc. That being said, we have a couple things we'll be rolling out, both in the apps and behind the scenes, likely within the next 30 days, which are looking very promising in our testing. Be assured that this is a priority and we are working on it. 

Reading the Silver Lining through the app requires a one-time registration by completing a contact form in the app. After that you can access any issue. There should not be any restriction based on the user's location. If you are still experiencing problems after registering, please post here with the specific details of the error you experience.

Currently, there are no plans to expand the website to exactly mimic the app functionality. We have limited development funds and 95% of all AC Central traffic is on mobile devices so that is where we focus our efforts. That being said, you can post this as a feature request and if it gets enough votes, it will be considered.
