BluOS app; flickering/fading user interface

Hi, - When browsing albums using the BluOS app on iOS/iPaOS the screen fades/flickers while (what it seems) album art is being loaded. At some app upgrade the fading of the app user interface was introduced and the problem was not there before. - When putting BluOS app in background on iPad and opening the app again, the album graphics on the current page is gone. It is necessary to scroll up/down a page or two for the album graphics to return. - Running on macOS Sequoia (M2 Pro) it takes about 15 seconds to start the BluOS controller app (slow startup got noticable when version 4.x was introduced). System setup: Node 2i player (Ethernet connected), BluOS controllers (iPad Pro M1, iPhone 13, Mac mini M2 Pro) on 802.11ac Wi-Fi. 19500 songs in library (SMB share on Ethernet connected Mac mini). Please test thoroughly before release. BR
