I appreciate your help, but it is not a solution accessible to the average person. I have no experience as a developer, and I have never done this in this way.

Ah, you have the Playstore version. You will need to wait for our next push to the Playstore for your update. No worries nevertheless, we are applying a fix. We genuinely and sincerely appreciate your patience and assistance. If you wish to uninstall and reinstall now, please feel free to go ahead and do so. Your rewards for this challenge will not be affected.
Good evening, I wasn't able to respond to your message promptly. I understood from your response that you were suggesting I wait for the new Android update for the Play Store or that it invites me to uninstall and install the APK version, something I'm not familiar with and that complicates everything a bit more for me.
Initially, you offered me manual payment of the reward, so I shared my LN⚡ address associated with my SOUND HSA account. I demonstrated, and you have confirmed that I have completed everything correctly. The error or failure is not my fault. Why complicate everything further and make me wait for a new update? A simple LN⚡ payment transaction would resolve everything in seconds and happily put an end to this inconvenience.
I suppose you are busy people like me, and with so many things to do, you might forget this as the days go by. The challenge is almost over, and when the update is available, it will be too late to claim the reward.
Please, I await your prompt response, thanks you.
