The date sorting issue is an known issue, which will be fixed soon.
For daily aggregation, I usually would suggest it done in data model, for example, by using a calculated column to extract the date. However, with PowerBI API we do not have a good way of changing the aggregation yet. Please help us to prioritize this
feature by adding your request at:

As a side note, in case comparing In House Sales and Ecommence Sales
by transaction date means anything to you, may you could consider using a combo chart to present both in one chart.
