Last update ruined my account!!

For the past 2 weeks I cant even log back into my Pokémon account. Every time Ive tried I just get a blue streak going across on the top of the page and NOTHING comes on. So now I lost everything. And now its asking to create a NEW account and STILL get that blue streak. What the heck happen with this last passed update?!!!

Be safe! about Pokémon GO, v1.27.4
