On multisend.mytonwallet.io/droppage, when opened inside the MyTonWallet app WebView (Android/iOS), the multi-send sample CSV cannot be downloaded.
The Blob + a.click() download method is blocked by WebView, so nothing happens when the user taps the button.

Expected

User should be able to download the multi-send sample CSV on /droppage.

Steps to Reproduce

1. Open MyTonWallet mobile app.
2. Long press the Send button to open the old design menu.
3. Select Multi Send (opens WebView).
4. Navigate to drop page
5. Tap “Download Sample CSV” — nothing happens.

Actual

Inside the in-app WebView, tapping “Download Sample CSV” does nothing.

Environment

Android/iOS WebViews block:

• blob: URLs
• programmatic downloads triggered via a.click()

Proposed fix

Add a “View Sample” button on /droppage that opens the multi-send sample CSV in a modal so users can copy it manually.
This works reliably inside WebViews
