A little hard to advise and help you when you provide NO information about your iPad.
Can you confirm what year and model iPad do you have/own?
The “A” model number can be found on the aluminium back of your iPad, in small print, right under the larger bold print “iPad”.
What iOS/iPadOS version is this iPad, currently, running?
All of that additional info can be found in the Settings app, General settings panel, About.
Also, can you confirm what year and model iPhone you are using and what iOS version it is currently running?
Please attempt to answer all questions asked.
Thank You.
