How do I upgrade my Nodle wallet?

Could you please elaborate on the steps required to upgrade my Nodle wallet? I'm seeking clear guidance on the process, from start to finish. Is there a specific version of the Nodle app that I need to download, or are there any prerequisites that I should be aware of before attempting the upgrade? Additionally, could you provide any insight into potential issues that might arise during the upgrade process, and how I can troubleshoot them if necessary? I'm keen to ensure a smooth and seamless transition to the latest version of my Nodle wallet.
