There is a message with a map, a clickable button, or else, to display the shared locations.
The location sharing does not stop when switching between applications.
A green map icon in the top right that just directs me to the profile page, and a message that says location streaming is enabled.
Tapping on it does nothing. Going into the context menu and checking Info doesn’t display location info.
Additionally, if I switch between apps before the time is due, I see a message saying that the location streaming has been stopped.
Steps to reproduce the problem
Open a chat.
Click on the attachment button.
See the message saying “Location streaming enabled”
Notice that there’s an OS indicator in the Control Center showing that the location is being accessed by Delta Chat.
That’s correct. I have at first checked the App Store released version (1.36.1 as you mentioned) at first, but thinking that there may have been further developments on less tested/nightly releases, I have tried the TestFlight version, which hasn’t been promoted to the store release yet.
If you’d like to try it out yourself, you can use one of the links on the official Delta Chat page.
Details of each build, if I recall correctly, are visible when you try to join on your phone, and afterwards, in the TestFlight application itself by viewing the Previous Builds panel of the application.
