I use an iPad that cannot be updated to iOS 13 and still uses 12.5.5. and therefore I can't use the Nimbus Note app. Is there a apk or another solution to still use the app? Other than that, the iPad works fine for me and I don't want to buy a new one just for that reason. What is unfortunate, that I also can't get access to my notes via a browser. There I am prompted to download the app.

Thank you for your time and help.
