We are aware that Enhanced SMS & Caller ID has stopped working recently. The issue appears to be that many of the libraries used by our application are no longer available. The app had been running, unsupported now, for about 6 years. Before we can update the application, we will need to first migrate it to the latest version of Android and applicable libraries.
Given the size of the effort required, we will likely also update the licensing for the application so it becomes subscription based (e.g. a nominal monthly or yearly fee will be charged to use the app). This should hopefully provide the means to keep the app and infrastructure running for many more years to come.
Please be patient while we work through the update. Thank you for supporting us!
