I’ve updated the app for first time in years and now I have a black screen whenever I open I’ve tried everything I cannot access at all and I have some important reminders I need asap! 
Please help!!
Hey there, is your Clear client still encountering this issue? If it has been years since you’ve updated it sounds like you are moving from the Clear 1 client to the new Clear which may cause some issues.
If you aren’t stuck at a black screen anymore - using the “Support” feature in Clear’s main menu will directly connect with us via iMessage to gather some more information!
