That is correct – this is a feature that we are likely going to add soon. Please see the list of supported cameras and features here: https://owlr.uservoice.com/knowledgebase/articles/458563-supported-cameras-for-owlr-apps.

PTZ for my old cam "Foscam FI9821W V2" worked fine (Android App "OWLR: Foscam", ver 184.108.40.206, using Andoid 9 tablet or Android 10 smartphone), but PTZ is missing for my new "Foscam R4M". This makes your Android app useless.
Please let me know if I can support update testing.
