RoseConnect does not display album

All of sudden since yesterday, no albums were shown in the Album view.
The albums were shown on RS520 but not in the Album view. If I clicked the latest played album, it played.
My iPad mini works fine
I have removed the app and reinstalled it without any luck.
I’m so frustrated with the software after 2 months of using RS520

The albums show on my iPhone again a minute ago and I did nothing but turn on the app again. HiFiRose did a good job making listening to music uneasy
