With 2026.4.1 the same, before all was fine.

Same here. Very noticeable on iPhone 26.4. Barely noticeable on Windows 11 Pro. Almost 1.5 seconds to display icons. I use card_mod and custom button cards; but this was fine pre 2026.4. Thank you.

Looks to be delayed icons so could be releated to Simplify icon loading by piitaya · Pull Request #29953 · home-assistant/frontend · GitHub

Same here. We are talking 10-15 sec to load dashboards on iOS. Pre 2026.4 below one sec.

I can confirm the slow behavior on iOS and Android as well.
