Why do I have problems displaying certain icons?

If the “+” sign between pack products, an availability icon or another icon appears as a square, ask the person managing your theme to check that its fonts and styles load correctly.

The module uses Material Icons, among other resources. For the “+” separators, its styles also specify the fallback font ap5-mu, supplied in the module’s views/fonts folder. A theme without Material Icons is therefore not, by itself, a sufficient explanation.

The correction depends on the theme and the affected icon. Check the result on the pack page and in the blocks where the icon appears.
