Now I did get support and it works again, but it had to be another issue. They say internet service provider, but for two days, I don't know, mobile phones did not work, notebook did not work, and now out of the blue it works again.

So let's say Amical did a good job, at least I did. Very fast reply, so I'm happy again. Thank you very much.
In the beginning I was VERY happy about this app Amical. Now, out of the blue, it does not work anymore since almost 2 days and NOT support answer to my e-mails with print screen. I get always "connection errors". It is a shame!! I assume, their server is down!
