App not installed error for User Company Communicator App (users are not recieving messages)

[Saraanuzzi]

We have been able to deploy the company communicator app.

As a part of testing we tried sending message to Team, where a test users were part of.
We are able to draft and preview the message in Author app. While trying to send it to the users via Team (M365 Group) we are getting error with no users recieving messages. On checking the report logs, it mentions App not installed for all the users, where as as logged in as test user, we can see the App present and can open to check for messages.

Sharing screenshot of Log report:

Hi @Saraanuzzi
Could you please confirm us whether you were able to send messages via 1st and 2nd option.

also Please confirm whether the issue affects only these two users or everyone. Also, could you check if there are any app policies restricting these users?

[Saraanuzzi]

Hello, @peddivyshnavi
I did some tests, created a new distribution list, inserted the two users and generated a new message without success.
The problem is affecting around 30/40% of the company, I used this log from my last test, but I am experiencing failure with a lot of users, including mine, mine is not receiving it.
The policy is enabled for all users in the organization.
An important point:
our users do not have permission to delete the app, so we can also rule out this hypothesis.

Hello,

Procedure carried out unsuccessfully.

I followed the instructions step by step and still have the same problems.

Hello @peddivyshnavi

After disconnecting and reconnecting the function applications, I carried out a new test and still have the same error.

Guys, our organization is very impacted by the incident, I need an alternative to be able to use the application.
And I don't know what happened, I can't view the chat on Teams anymore

Hi @Saraanuzzi, Can you please send the Failures screenshot ?
TO do this
Go to resource group where CC app is deployed --> Go to Application insight type resource --> Go to Failures section from Left hand side menu --> share the screenshots and stack trace for Top 3 response codes and Top 3 failures

[Saraanuzzi]

Hello @tiwariShiv7

Failures follow as requested.
I would like to point out that my case was already being analyzed by @peddivyshnavi e we have already gone through this stage.
I would like to suggest that we implement CC again, I believe it will be faster and maybe solve the problem.

[tiwariShiv7]

Hi @Saraanuzzi Thanks for this. One more thing can you also check Reason for the failure by exporting the sent message data and send us the screenshot?

Good afternoon.

Hey @Saraanuzzi , Thanks for your patience. Last we checked you tried to reconnect and sync again. Can you please send us the screenshot of error from Failures once ?

Go to resource group where CC app is deployed --> Go to Application insight type resource -->Under investigate section Click on failures --> share the screenshot and stack trace for Top 3 response codes.

Hello, I managed to resolve the error I was getting before by uninstalling and installing again.
