Hey @Petra89, thanks for reaching out to the Community!
If your address doesn't autocomplete, enter it manually and select Find.
If you still can’t find it, select your building, street name, or a close public space or building.
Note: Don't use someone else's address.
You can also try this using a different browser or private browser.
If you're still having trouble, send me a screenshot of what's happening when you attempt to enter an address and select Find. Make sure to hide sensitive info when posting to the Community.
Let me know how this goes!
