I have a line chart in my app which was previously working fine, but now appears to be broken.
When opening the app in Edit mode, the chart initially appears to be working, but then on changing any of the Series under the Items property an error is generated.
The chart's Series 1-3 should take their values from labels in a Gallery used to calculate running totals as shown below:
The series 1-3 in the image above correspond to the values of label controls in the gallery as shown below:
However, on attempting to change one of the series properties, the gallery controls no longer appear as options in the dropdown:
Then, on selecting another option for the series, the error message "Expected a different collection record structure" appears against the line chart's Items property:
The chart has previously been working (and modified) with no issues over the course of the past 18 months until now. This makes me think this could this be a recently introduced bug in PowerApps studio - or am I missing something obvious?
