Hello,
Usually, when an update comes out, I always wait at least a week or 2 before updating the theme. (in case something goes wrong and you release a patch some days later)
So it’s possible that when updating the theme, there were already 2 new updates.
Also, I’m not working on my website every day so maybe the problem was here before the last update in June and I didn’t see it because I was only checking the desktop version on my computer.
I remember that I have checked my site on mobile on May, and there was no problem at that time.
The last time I checked on mobile was end of June and I saw the problem appeared.
So I can say safely say that last version of Xstore that worked fine on the mobile version was the version 8.1.5 / May 03, 2022.
The versions released after May 03, 2022 may have caused the problem on mobile, but I only realized it on end of June checking the mobile version.
So, you can compare the version 8.1.5 / May 03, 2022 with my actual version.
(Is it a way to rollback to the theme version 8.1.5 released on May 03, 2022 ?)
Hope it can helps.
Regards
