I use Firefox or Firefox Focus as my phone browser and links don’t seem to work
If you are using a Firefox or Firefox Focus browser on your phone you might be having some trouble using any of the links that are are shared from the Frugl Grocery app including if you choose the login via email option which will send you a link to give you password-less login.
In short this is not an uncommon problem and not something to do with the Frugl Grocery app but something that happens with all Deeplinks (also sometimes known as Magic Links) that are becoming more common in apps. In short a Deeplink works like a file association on your computer where your PC knows that if you click a particular type of file to open a particular application. Deeplinks are just like that, but for your phone.
Firefox and Firefox Focus actually have some settings that are enabled by default that will prevent you using any deeplink for any application (not just Frugl Grocery). To resolve this check out the support article from Mozilla for how to fix
