I have a problem with calendar on my Verizon Galaxy S10+. MS Exchange with Outlook. All day events are ok on Outlook on my work, laptop, and home PCs but show one day earlier on my GS10 stock calendar (I guess that is Google.) Other calendar items are OK. Only all day events are affected. I ran across a forum from 2016 which addressed the same problem and this was a Google server issue back then which got fixed on the server end. I also posted on the Verizon forums. Would appreciate input on fixes. I already uninstalled and reinstalled calendar account. Thanks!
