Thank you BitMaxz. Where exactly can I access the option menue in the mobile app? Is it: accessing a wallet and then chosing the concerning transaction and then chosing "details"? I tried, but there is nothing. And there is no other menu or option to access info related to the transaction.
I tried to access the wallet via desktop app (I have seed and pwd), but couldn't retreive the private key yet. I'll try within the next days and let you know if it worked.
Thanks so far!
