With the current full version, 3.00.241 the logo should be fixed for both HTTPS and no link. The logo image is permitted.
Selecting your running listings in Sixbit and “Revise|Send Revisions to Site” is all that is required to rebuild the description with the compliant logo. (or removal if subscribed)
Unfortunately the eBay checks aren’t run immediately after revisions, so you won’t see the count go down until they re-run it. We’re trying to get some clarification on how long that will take, and if it can be initiated on your end.
