Hello,
we returned back to the latest version of theme and core plugin
but we need few more steps from your site to check (sorry but we are looking for the problem in such way only)
1/ Check if the sidebar off canvas on shop mobile will be disabled (like in previous task we sent before)
If there is no problem if not canvas sidebar on mobile please,
2/ enable mobile canvas but disable sticky sidebar and check again
Hope steps are described in correct way for understanding.
Regards
