Comments disappeared from shared albums

Hi slava06,

If you are not seeing comments from shared albums, the guidance below can help:

1. "Check the System Status page for issues affecting Photos.
2. Check the Internet connection on all your devices by going to apple.com and iCloud.com. You need to connect to the Internet to make a comment.
3. See if the number of comments is the same on your iOS device and your Mac or PC.

If you have an active Internet connection, and a photo or video has a different number of comments on multiple devices, try these steps.

On your iPhone, iPad, or iPod touch:

1. Close the Photos app. If you're not sure know how to do this, follow these steps.
2. Tap Settings > [your name] > iCloud > Photos.
3. Turn off Shared Albums.
4. Tap OK. The albums and photos will automatically be added again when you turn this setting back on.
5. Go back to the Home screen. Wait about a minute.
6. Tap Settings > [your name] > iCloud > Photos.
7. Turn on Shared Albums.
8. Go back to the Home screen.
9. Open Photos and tap the Albums tab. 
10. Tap the name of the Shared Album.
11. Check the comments on the photo or video.
