Sticker crashes Telegram apps

Telegram actively deletes and bans bugged sticker. However, it may still be cached in the app.
With official apps, you must wait for an update. But Swiftgram has recovery options that you can use if app crashes on launch.

How to clean caches?
1. Close Swiftgram (swipe it up)
2. Go to iOS settings > Applications > Swiftgram
3. Enable "Reset Metadata"
4. Open the app again
5. Wait for the app to complete cleanup. It may take several minutes.
If it does not work, enable "Reset All" instead of "Reset Metadata".

What will be deleted?
Secret chats, Media cache and some local settings (like proxies and themes)

Will it delete my accounts?
No, it will not delete your accounts. But this is not an officially supported way of cleaning caches, proceed at your own risk.

What to do if app still does not work after Reset Metadata and Reset All?
Wait when Telegram will provide a fix and it will be merged to Swiftgram, or to re-install the app.
When Swiftgram update?
