my text screen is stuck in landscape mode but my portrait mode lock is off and it will not rotate when i turn the phone sideways

If you are certain that the Rotate Screen Lock is unlocked, then Try and Force Restart your iPhone EXACTLY as shown below and see whether that resolves the issue:

• Press and quickly release Volume UP button
• Press and quickly release Volume DOWN button
• Press and Hold the SIDE button until an Apple logo appears and then release the Side button (Can take up to 20 seconds. (DO NOT release Side Button when invited to Slide Power OFF).

That didn't work at all. Tried it several times. This is SO frustrating. Seemed to start with last iOS update 17.3.1
