Could you let us know which Topical Study this was?

We have noticed this issue too and the developers will be working on fixing it soon.

Thanks for letting us know. Something must have broken that during other changes the developers are making because it worked before. They have been notified and are looking into it.

That is not something we have looked into at this point, but if there is enough user demand for it (upvotes on this idea), we will talk to our developers to determine cost and feasibility. 

Just an update on this. Our developers have worked on this off and on over the last several months but unfortunately, they tell us that the Silk browser is notoriously outdated, buggy, and Amazon provides no dev tools making it essentially impossible to test anything without doing trial and error releases, which is not a good way to work. Scrolling the Congregation list is possible but only by using a "click and drag" procedure where on the Firestick remote you hold the round center button and simultaneously hold the up button. Doing this repeatedly will get you through the entire menu. Not ideal, but it is the best we can do. Frankly, it is quicker to just use Search to filter for a congregation. We are going to mark this Fixed to close the issue since we won't be spending any more resources on it unless Amazon improves Silk at some point.

On a more positive note, AC Central works really well on the other smart TVs (Samsung) we've tested.

What version of Android are you running? So far we have not been able to replicate this on our Android test devices so any additional info to help us isolate the issue is appreciated.

Scrolling the congregation list works correctly on all current mainstream browsers we have tested. Are you using a Mac or Windows computer? What version of the operating system? What browser are you using and what version is it?

Starting with the 4.0.6 app update, you will be returned to where you had scrolled in the list, not start over at the top. This applies to all areas of the app. However, when scrolling through a long list of items, there will continue to be a periodic delay as the app needs to dynamically fetch new data from the cloud. This ensures the user always has the most current information.

The 4.0.6 app update includes a new setting where user can increase the text size.
