@Gabriela614
I see what you mean Gabriela, although I do not speak your language I can see that screenshot is for a confirmed reservation but half the information on the left side of your message stream has been deleted or is missing.
I have not seen what you are experiencing before. This is not general amongst users and I would suggest you contact Airbnb to see if they can help restore this for you.
It may be a problem on your end where you computer has become 'lazy' and is not loading information fully from the internet. If that is the case try deleting your cache and the next time you log on your computer will be forced to fully download your Airbnb pages from the internet.
Other than that, you may need to get help from Airbnb. I cannot find an Airbnb contact phone number for Czechia and it may be that you have to contact them through the Vienna number which is +43 72 08 83 800.
Interesting problem Gabriela, I hope Airbnb can sort it out for you.
Cheers.....Rob
