Difficult to get Android apps to Jolla Store [answered]
I sent an email to the developer of the Helsinki Airport app for Android and asked if they could send this app to Harbour for testing. I have given up asking devs for native ones because the answers haven't been that positive but I usually mention that anyway.

Looks like a pretty simple app that one would think it would work but they answered:
Translated summary: "Jolla doesn't support Google Services...This app crashes on Jolla"
"Valitettavasti Jolla ei tue Google Servicejä, joita Android sovelluksessa on mm. GPS-paikannus, jota käytämme sovelluksessamme. Tällaisen appsin käyttäminen Jolla-puhelimessa kaataa sovelluksen. Tämä kaatuminen hyvin todennäköisesti aiheuttaa sen, että sovellusta ei hyväksytä Jolla Storeen. Toistaiseksi emme siis ole laittamassa Android-versiota Jolla Storeen. Kiitos kuitenkin hyvästä ehdotuksesta!"
Sad but true. Hoping the next release will add support for basic apps like this. Then again a more complicated app like Collector for ArcGIS works perfectly including positioning. https://together.jolla.com/question/63151/support-for-05m-positioning-accuracy-on-jolla-in-finland/
