Telephoto setting broken, dev not responsive – DoubleTake by Filmic Pro Review

I want to use this app for one thing, and that is to capture the telephoto and the normal lens on an iPhone 13 Pro for quick interviews so I have an A and B roll to edit with. Unfortunately, the telephoto mode goes into a 2X crop effect (but looks just fine in Preview mode), which of course throws off the focal lengths of the lenses and makes shooting with it difficult. I filed a report with the dev via their website and even sent them screenshots, demo footage, and a description of the issue, and never received a response. Disappointing, to say the least. The premise of this app is sound, although basic and lacking many features. It seems pretty clear they are putting all their development time into their main app, but this ONE THING I need to use this app for doesn’t exist in that app yet, either. I would love to be able to use this app but as it stands now it’s not possible.
