URL Mappings do a 307 to http, then 301 to https - redirect chains

All of the URL mappings I have configured in squarespace do a 301 redirect from the old slug to the new slug on HTTP. Then the new slug on HTTP corrects to HTTPS via 307 redirect. I haven't found any other forums with the same issue. 

Example: 

URL Mapping configured: 

/insights-innovations -> /blog 301

Resulting redirect chain: 

Expectation:

The 301 redirect to http:// shouldn't happen. It should just do a 301 to the new slug on https://

Any update? I have the same question. I would expect the 301 from an https slug to redirect to https

No solution yet unfortunately
