Yotpo: Product Reviews App

Can someone please assist? Been a Yotpo-paying customer for years. I logged many email requests for support. Tried to talk to a bot and can't get any support. Please help me or send csv file of reviews to import into another Review app. My app is not opening for days now and only gives a blank screen. Very frustrating not to access my reviews and even more frustrating not to get any help. I tried all available channels for support many times now. Hope to get some help here
