Searching with word starting with letter "A" on BlackBerry Hub causes the Hub to go blank.
Searching with word starting with letter "A" on BlackBerry Hub causes the Hub to go blank even when there are emails that start with "A". The phone has to be rebooted because the Hub stays blank even when closed and started again.
Words starting with " B to Z" seem to search fine.
I have a KeyOne with April 5, 2019 update. Latest Hub update installed
I believe it might be tied into "Firefox" update (this morning), however not 100% sure.
