Targeted notification doesnt work on externals

Question

Hello, I actually have 2 questions in 1:

I uploaded my app to another tenant's catalog (Using the graph api).

I then used an api to add the app to a teams chat, and it worked (without installing the app).

So:

1. I guess adding the app to the chat automatically installs it there?

Then I tried to send a targeted notification to an external user and it didn't work.

So:
2. I have an assumption that it takes time for it to work after we upload the app? Because it does work in another tenant I tried it. If Im right, how much time it takes for the app to full work after adding it to the catalog/install it?

Answer 1

@Shahar Sonsino - Thank you for bringing this issue to our attention.
1.Yes, when you add an app to a Teams chat using the API, it typically installs the app for that chat. This is why you were able to use the app without explicitly installing it first.

2.There can be a delay between when you upload the app to the catalog and when it becomes fully functional. This delay can vary depending on several factors, such as the propagation time across the tenant's infrastructure and any caching mechanisms in place. While there's no exact time frame, it usually takes a few minutes to a couple of hours for the app to be fully operational. If it works in another tenant, it suggests that the app itself is correctly configured, and the delay might be due to these propagation factors.
