Extension conflict in Safari between PtK and Capitol One Shopping

I am running PtK 2.6 as a paid subscriber, using the Safari (14.0.2) extension under Mojave (10.14.6). This morning, I installed the new Capitol One Shopping (formerly Wikibuy 1.0.6) extension. and it prevents 2.6 from working. The PtK toolbar icon tries to open the PtK page, but then hangs.

P for K 1.6 still works.

PtK 2.6 will work if I uncheck the COS extension - that is, I don’t have to uninstall COS to get 2.6 to function properly.

Thanks for the report. We’re going to see if we can reproduce this problem. Will update here when we know more.
