@GiannisK I have been in contact with the engineers, the issue seems to come from an app update.  They have shared an apk for an older app build that resolve my issues.

You can find it here. https://static.tp-link.com/upload/beta/2024/202409/20240923/Tapo_3.7.113(4113)_20240919022100-tapo-trial-dist-release.apk

See if this resolves your issue as well.

I am waiting to see when they think this fix will be out on a public build.

  @glyn hello, much appreciated that you shared the information. I have installed it immediately after your message and the app is working without any problem until today.

Thank you very much!

Thx for this bug, all my customers using this camera was upset about me; even my mom...
Otherwise, i updated the app and it's at new running correctly.

Is there a way in the app to add the rtsp link directly into to avoid using your servers ?
I've got dyndns on my connections and i can open ports (NAT)

  @glyn i am happy to hear that the bug was fixed. I will keep the apk for back up solution.

Thank you for the informations. Have a nice day.
