Telegram App

Hey maro_vioron,

What happens if you open the app on your iPhone like the alert shows in the image you sent over? If it doesn't provide on-screen steps or indications it's syncing, we recommend the following steps to see if the app starts syncing between your devices:

1. Ensure your iPhone and Apple Watch are updated as updates help with installing bug fixes and security updates. If an update is needed, back up first. Update your iPhone or iPad - Apple Support and Update your Apple Watch - Apple Support
2. After ensuring both devices are updated, check for app updates and install any available: How to manually update apps on your Apple device - Apple Support

If the app is still not syncing, we recommend reaching out to their support to look into the app more. Here's how to reach an app developer, just in case: How to contact an app developer - Apple Support

Thanks and take care!
