I think I have either a solution or workaround! Grok suggested the following and today it seems to have worked!
Quote from Grok:
“The repeated welcome screen suggests the app fails to save its state properly, which can trigger ongoing initialization overhead.
• Try force-closing Notes, then relaunching and dismissing the screen multiple times in quick succession.”
So, having already tried other suggestions such as toggling my Apple ID (sign out/sign in) and performing a complete reset of my iPad data … the above worked! Took at least 15 relaunch/dismiss/close cycles … but now Notes opens to the last folder or note in use and all my Notes-based shortcuts are working again! Phew.
Grok later gave me more on why this worked:
”This outcome indicates that the issue was likely tied to a corrupted or stuck app state cache, which multiple rapid closures can sometimes clear by interrupting incomplete initialization or background processes.
Regarding the steps you have already taken—toggling your Apple ID (iCloud sign-out and sign-in) and performing a full reset of all settings—these are comprehensive measures that address potential sync conflicts and system configuration corruption. The fact that force-quitting ultimately succeeded suggests the root cause was localized to the Notes app’s runtime state rather than a deeper iCloud synchronization or global settings problem.”
