Sometimes on some timeframes drawings are not displayed. For instance, I am on 3h timeframe, I draw a trend line, or horizontal ray, or box. I don't see it on the chart, but if I change to other timeframe I see it.

Hello @Marco Monti! Thank you for contacting us.

This can happen with custom timeframes.
If you run into it, please add the custom timeframe again first, and then add the drawings once more. After that, the drawings should appear on that custom timeframe.

If it happens again, feel free to message us.
