Hard @calm to keep calm. Just renewed my subscription at £44 and the app has suddenly stopped working! It is money that I can not really spare, but did for this, but feel scammed out of it. Refund please.
Oh no, so sorry for your troubles.
If you can first delete and reinstall the app to see if it comes back.
