android app - no icon

Hello everyone, I am having an issue and have already reported it to jolla but because of the situation they are in they have not been able to confirm when it will get fixed (i am affraid it will take too long and i really need this particular app). I still hope there is a way to fix it manually by altering some files on the device itself. It's just that I am not an expert in this field and have not been able to figure out how. Now I hope someone can help. What happened is that I installed the SmartBanking app : https://apkpure.com/smartbanking-sk/com.zentity.sbank.csobsk Installation proceeds as usually and app gets installed and can even be run from the installer without any issues. It even shows up under apps in the Aptoide store. But what is missing is the app icon and therfore it is not possible to run the app at all. This is what I would like to get fixed. Anyone any ideas or suggestions? Thank you in advance! Richard
