I am currently facing a issue with Product gallery. I am not able to add a gallery images for the single product as the gallery section is not visible at the backend, earlier it was there but currently it not showing so please let me know what the issue is.
Please deactivate all the plugins not related to the theme and switch the parent theme, check the issue, if the problem remains, leave the plugins not activated and provide the site admin access to the private area
As soon as I have deactivated the plugins not related to the theme (for 5 minutes max) I saw the option to add the product gallery https://prnt.sc/t020mb
I have activated them. Deactivate and activate one by one checking which one causes the problem.
