hey hey!
I am currently working on a woocommerce shop and have a problem with product variations. the bug is not easily reproduced, thats why i am clueless right now.
in the shop there are multiple products (e.g. studiopapaya.de/produkt/workshop-gift-card) that have selectable variations (e.g. gift card prices) on one product. on some rare cases the dropdown opens up but just shows the white background like this:

the options are still selectable and you can add them to the cart and proceed to the checkout - its just the dropdown that is not showing the options. what confuses me is that there is one product (studiopapaya.de/produkt/gift-card) that is working on all the devices that otherwise show the bug.
i tried a lot of scenarios for bugfixing:
- on windows/macOS/samsung phones and tablets/iOS (samsung devices seem to have this problem most)
- on different browsers like chrome, safari, edge and firefox
- deactivating all plugins
- wordpress, laytheme, the woocommerce database and all plugins are updated
- disable all custom code
- deleted the cache in wordpress and in the browsers everytime
to make this even more illogical i tried the following:
- create a new product with variations
- check on device that did not show the variations for now - it's still not working
- disable all plugins
- check on the same device - its working now
- activate all plugins
- check on the same device - its still working
- check on another device that had the bug - its still not working
when i repeat this on the next device that was not working before, its working in the end. but all other devices are still not working. this might sound super confusing, but i hope i described it as precise as possible.
any help figuring out this problem would be appreciated!
Thanks a lot!
