If I take a video with my phone or other recording device and I'm not using the Palace app, can my owners still view it on the owner portal.
Yes. You will need to manually upload your video to your youtube channel manually, but you can then copy and paste the hyperlink to the video in the property diary. Create a diary entry (type: hyperlink) and paste the youtube link in the hyperlink area.
You need to enter the following in the description area or it will not work:
Inspection - Video Link
Once you've done that, and clicked internet transfer, your owners will see the embedded video as part of the owner portal.
