This is interesting.
I did not submit the app to the Jolla Store yet, as it still does not follow all guidelines for the store (such as retrial if network error, erase all comments and tests from the code, support for various devices, etc…).
Regarding this, I only followed the Organization name standards suggested here by @vige . I based the name on my username and .org after seeing other folders with the same structure on my device.
One thing I learned thanks to you, is to have the app tested by others before releasing it. Before this last release I got it tested by three members (that never had the app before) so I was sure it would work.
If it still does not work for you, send me a message and I will find a solution.
