Updated to new one ui 3.1 . Now I lost chromecast support, smart view is basically useless. Samsung why can you leave things alone. I don't love my tab s7+ anymore.
Also I can no longer open 2 different spreadsheets at the same time in split screen view. This is annoying as now I can only open the sheets app once, and then open excel if I want 2 spreadsheets open at the same time side by side. Infuriating, the apps behav slightly different and I have to always be wary of what app I opened a spreadsheet in.
