I used to be able to access Samsung Notes on my Windows computer, but now it's restricted to Samsung-branded PCs only. How can I ensure that my data remains accessible on my phone and usable on my PC?

You can accomplish this by syncing your Samsung Notes with Microsoft OneNote if you've been using Samsung Notes to store significant folders, notes, and tasks and want to ensure easy access to this information on both your Samsung Galaxy phone and your PC. You can access your notes on all of your devices thanks to this synchronization, including by viewing them in Microsoft Office on your PC. Take the following actions to configure this synchronization:
• Launch the Samsung Notes app on your tablet or Galaxy phone.
• Tap the Menu icon, typically a trio of horizontal lines.
• Click "Settings"
• Then click "Sync to Microsoft OneNote."
• To begin the setup, click "Get Started".
• A prompt to sign in to your Microsoft Account will appear.
• Pick the folders you want to sync; the OneNote icon will appear next to the synced folders.
• Toggle the switch at the top to enable sync before going back to the previous screen.
• The "Sync now" option lets you manually sync your folders.
• You can also choose to sync using just Wi-Fi or both Wi-Fi and mobile data.
• You can also choose to enable syncing while roaming, which enables you to access your content while using roaming data.
• From this settings menu, you can sign out of your Microsoft account if necessary.
• Now, on your computer, log in to Outlook using your Microsoft account. To view your synced notes after logging in, choose the OneNote feed icon in the top right corner.
Remember that even though OneNote on your computer allows you to view your notes, editing or deleting notes from Samsung Notes must still be done through the Samsung Notes app.
