GPT on Android reverts on multimodal from 4 to 3.5 after one prompt

Just what the title says.

Every single time I use GPT on Android (14) Samsung Galaxy S23, after a single prompt it reverts from GPT 4 to GPT 3.5

This essentially renders GPT for mobile useless, because any session is ruined the second I need more than one-shot.

It isn’t a random occurence; it’s every single solitary session.

Just tried; the same issue occurs after every prompt.
