Adaloのプレビューを表示すると、画面が真っ白になってしまいます。実際のスマホにアプリを取り込んでみても、同じく真っ白です。他のAdaloのアプリはプレビューは問題なく表示されます。  
真っ白になっているほうのアプリは、一から作り直すしかないのでしょうか？

もしimage componentなどで、Placeholderを設定していると、このような事象が発生しているようです。。（原因はわからず、、）

Hi @nekotabetai,

“White screen” usually means that app has crashed.  
Most frequent reason for it, as I observe, is a problem with some of the components on the particular screen. In rare cases the reason could be the flaws of the logic in the app (though this is quite rare - Adalo is robust in that respect).

Seems that your problem is similar to one mentioned here:

Best regards,  
Victor

placeholderの画像を消したら動きました。何かの不具合みたいですね。今日もう一度Adaloを見てみたら、直っていました！ありがとうございます。
