**EDIT*************I've bumped up my review from 1 to 4 stars. Reason: I found that I needed to raise my issue (bug report) as a 'purchase issue', so once I've done that, Duolingo were in touch with a proposed solution within 48 hours. I'm glad to say the solution worked for me. So - if you have an issue with your Super Family subscription, where you have issues with your invite link. just Google 'Duolingo bug reporting' then fill in the form, but select the 'Purchasing issue' option. ************No support, broken app. I purchased the Super family subscription, to add my kids and wife. Paid for the subscription, but impossible to add my family. The app is broken. I'm highly IT literate and have tried all solutions that I could find. Also impossible to contact Duolingo support, there's a support email which takes a detective to find, but then no response. So.... I've paid dearly for something that doesn't work and Duolingo can't be asked to help. Your reputation can't last like this....
