Hi there! I understand your CollaNote app is crashing every time you open your notes on your Mac running OS X 10.15.7. Let’s see if we can get this sorted out together.

Could you tell me a bit more about when exactly the app crashes? For example:
- Does it happen immediately when you open the app, or only when you try to open certain notes?
- Have you noticed if it crashes with all notes or just specific ones, maybe larger files or those containing images or PDFs?
- Have you recently updated the app or your Mac OS?

Meanwhile, I’ll guide you through some initial steps that often help solve such crashes:

1. Restart the App Completely: Quit CollaNote fully (use Command + Q or right-click the app icon and choose Quit), then reopen it. This can clear temporary glitches.

2. Update the App: Make sure you have the latest version of CollaNote installed from the Mac App Store, as updates often fix bugs.

3. Check Your Notes: Sometimes, specific notes with heavy content like images or PDFs can cause crashes. If it crashes while opening a particular note, that note might be corrupted or too large.

4. Backup Your Notes to iCloud: Before doing anything drastic, back up your notes to iCloud if you haven't, so you don’t lose any data.

5. Reinstall the App: Delete CollaNote and reinstall it. This has helped other users experiencing similar crashes.

If after these steps the app still crashes, I can guide you through more advanced troubleshooting such as checking for corrupted notes or log files.

Does any of this match what you’ve already tried or noticed? That way I can tailor the next steps perfectly for you.

It's on my iPad, I tried restarting it and clearing the cache and nothing has worked

Thanks for clarifying that you’re using CollaNote on your iPad and that restarting and clearing cache didn’t help.

Since you’ve already tried those basics, let’s move on to a few more focused steps:

1. Force Close and Reopen CollaNote: Sometimes, a full force quit can clear deeper glitches. Double-click the Home button (or swipe up from the bottom on newer iPads) to view all open apps. Swipe up on CollaNote’s preview to close it completely, then reopen it.

2. Check for App Updates: Open the App Store, tap your profile icon, then scroll to see if there are updates pending for CollaNote. Installing the latest version can fix bugs causing crashes.

3. Backup Your Notes: Before uninstalling, make sure your notes are safely backed up to iCloud or another cloud service. This is crucial to avoid data loss.

4. Delete and Reinstall CollaNote: Long-press the app icon, tap “Remove App” then “Delete App” to uninstall. After that, reinstall it from the App Store.

If after reinstalling the app still crashes, it could be a problem specific to certain notes or a deeper software issue. In that case:

- Try to recall if the crash happens only after opening a particular note. Corrupted notes can cause crashes.

- If you can access the app even briefly, try exporting or sharing individual notes in smaller batches to isolate any problematic files.

If none of this works, please let me know, and we can dig deeper or consider reaching out to CollaNote support with crash logs.

Does this sound good to you? I’m here to guide you through each step.
