Hello,
thank you for your advice, everything is working now, even though the Astra template is still active. It wasn’t the fault.
Thank you very much for the advice. We have disabled the plugins, added the shortcodes, but the problem persists, not only on iPhones, but also on Mac, it simply does not work on iOS. Deactivating any of the plugins did not help. Do you have any other ideas about what to do with it, please?
