Save failed 13016

Hi

I got save failed -13016 when I export files on my Samsung s20 ultra with latest software.

This is very annoying. Why could you not have an error message that is understandable?

What does this error message mean and what should I do.

Also, could you please add the possibility to store the app storage on memory card instead on internal memory. The app is consuming 40+gb memory on my phone, which creates problems. Much better to store the dB on memory card.

Thanks

Lara
