Welcome to the community. 
I think you will need to specify the error message. I did find the app in App Lounge on my FP3+ running /e/OS (Android 10) v.1.2 if this is the app icon:
thanks for your quick reply. This is indeed the app i am looking for. By typing "tl " (space needed after tl) i do find the app in the list of proposed apps, but somehow i can not click on it (though i can click on all the other proposed apps). Error message is (in French): “Quelque chose a mal tourné! Veuillez réessayer plus tard”. Could you try to see whether you have the same problem? Could it be that the app name is too short?
I find the app without the space, just by searching for “tl”. I am able to install it (it seems unresponsive first, but then the “Install” button becomes a “Cancel” button, so it is installing … but very slow right now.
I actually cancelled the installation, went back to the search and went into the tl app description first where I started the installation anew. That worked without problems then.
I actually can’t even get to the install button, when I search applications i only get a list with text (see screenshot)
