So I have read all the foregoing and I found a similar issue, App worked fine on Samsung Galaxy A33, photos all good, as others mentioned moved to a Samsung Galaxy tabe A8 for easier working with my various locomotives and was equally unable to take photos or access library. Having read this, yes one was Android 13 and the new tablet Android 14. It has taken me a few days to find this 'App permission issue' (silly me thinking that I would find the answer as something to do with images or photos!).
Any way as others have asked just when is the release of 1.3.1 going to be? It's over two weeks since last response on this.
I am hesitant to load all my locos as many will be operated via the dongle in case the release happens to overwrite my specific loco information.
By the way I haven't found the sound profile maps for TTS to be very helpful, I find it quicker just to go to the original TTS Sound instructions sheet & amend the descriptions and apply the most appropriate graphics for each Function.
