Hi there! I see your Inkpad Notepad app froze after copying a large email content. Let me help you get it working again.

First, just to clarify:
- Are you still stuck with the app frozen on that note, or can you still navigate within the app?
- Have you tried closing and reopening the app already?
- Is there any important unsaved data in Inkpad you want to preserve?

With that info, here’s a straightforward way to try resolving the freeze issue:

1. Force close the Inkpad app on your iPhone:
- Swipe up from the bottom of the screen and pause slightly in the middle (or double press the Home button if you have one) to open the app switcher.
- Find Inkpad Notepad and swipe it up off the screen to close it completely.

2. Restart your iPhone:
- Press and hold the side button and volume up/down button until you see the power off slider.
- Slide to power off, wait 30 seconds, then press the side button to turn it back on.

3. Open Inkpad again, but avoid immediately opening the problematic note or pasting large content.

If the app still freezes after that:

4. Open Inkpad’s Trash or settings to see if you can delete any large notes or unsaved content that might be causing the problem. According to Inkpad's support info, you can open the menu icon (upper left corner) and choose "Trashed Notes" to manage saved notes.

5. In case large notes are causing slowdowns, try to split or reduce note sizes.

If this doesn't solve the problem or the app crashes persistently, we might consider deleting and reinstalling the app—though be cautious as this can remove unsynced notes unless you have them backed up.

Let me know how it goes after these steps and if you need help with syncing or backing up your notes before reinstalling. Are you satisfied with this initial guidance?
