As far as I know, currently the only way to see if I am subscribed to a filter is that I have to individually go to the manage subscriptions section of each filter and see if I have a subscription to that filter. If I am subscribed to someones shared filter and I did not favorite it is even more cumbersome to find out what filters I am subscribed to. I am wondering if there is any easy way to just pull up a list of all my subscriptions and to be able to manage them from that list?
Within the native Jira code, there currently is not an easier way to manage your subscriptions aside from the method you have described. However I did come across a 3rd party plugin for Jira that appears to offer improved subscription management features like what I think you are looking for.
Take a look at Subscriptions for Jira - Filter Manager. At this time it looks like this is only a Jira Server plugin, I don't see a Jira cloud version available at this time, nor can I seem to locate any Jira Cloud plugins that can offer this kind of functionality at this time.
