Update no longer supports pre iOS-13
No thanks for pushing out an update with no warning that it would make it inoperable on older versions of iOS (i.e. pre-13). If I had known I would not have updated it and would’ve simply continued to use the legal app. Most service providers recognise the need for more agnostic apps that work on older operating systems, or at least leave older legacy versions in the App Store for these users. You are an app to monitor electricity usage, allow bill downloads, accept refill orders & receive payments, it’s hardly the stuff of Fort Knox nor relentless upgrades. By comparison my NZ mobile phone co apps do all the same things yours does, but they get an update once in a blue moon (they know if it ain’t broke don’t fix it) and they always support older iOS by retaining legacy versions.
