Solo battles Inventory empty

Hello, after the guild boss update the gear changing mechanism in Solo battles wont load the inventory.
Some players replied to my concerns that they are able to access it after few seconds ( longer than before) but in my case i used a timer for 3:45 minutes and yet it wont load.
I tried hard refresh on Pc, clearing cache in my phone but nothing works.
Yesterday it worked after several refreshes but today, same thing.
