Hi,
On my FP6 preinstalled with /e/os I cannot locate the app “Jortt”. A friend of mine who owns a FP4 is able to find it.
I tried the suggestion to disable fake location and fake ip (which were not on anyway) but it did not help. I also tried searching for nl.jortt.JorttMobile as that seems to be the full name. In the Aurora store it is the same. All other apps I can find without a problem.
I am using anonymous mode in app lounge.
Play store page to app is https://play.google.com/store/apps/details?id=nl.jortt.JorttMobile&hl=nl
