I appreciate the info, this makes sense.

As far as the last part, I shut down all the apps on my iPad and rebooted it. I restarted it and opened only one tab in Safari on my bookkeeping website and opened one other app to get the info from. When swiping back-and-forth it fully reset the tab in Safari, deleting the numbers I entered.

Thanks again everyone for all of your help and allowing me to vent.
Does it happen only when you switch to that particular app? If Safari doesn’t refresh when you switch to a different app, then that app may be hogging resources for some reason.
(Side note- some apps also are coded badly and refresh every time you switch away from it for even a moment. I remember Gmail app would do this when you did a search, all the results would disappear and it would reset to inbox every time. I think they fixed it but this was a problem for years.)
 
<snip> One of the main things I wanted to do on the iPad instead of the iPhone is bookkeeping. This requires me to swipe between a couple different apps and Safari. In Safari I am logged into my bookkeeping software‘s website, which is web-based as you could assume.

I enter information into the forms on this website, I swipe to other apps to get that information. Invoice numbers, total amounts, fees, net amounts, etc. I copy the numbers and then swipe and paste them.

But on the new iPad that doesn’t work. Every time I swipe away from Safari and then return to it, all of the numbers are gone. The forms are completely reset. It’s reminding me of the older Safari where it used to get dark when you return to it when there wasn’t enough memory.

Is there anything I could do about this? I tried to do split screen, but neither of the two other apps that I get the information from are supported. I would really hate to have to spend a lot more money on a better iPad just so that it could remember the numbers I paste it into a form. Everything else about this iPad works perfectly fine for me.
Two ideas come to mind:
i) Apple improved the privacy features by blocking cross-tracking by default. You could check in Settings / Apps / Safari / Advanced (?) if the "Advanced Tracking" protection is "On", and if turning it to "Off" might fix the refresh issue
ii) try a different web browser. E.g., iCabmobile offers the option to turn "background refresh" to "off". You might want to contact the developer of iCabmobile (who is usually quite responsive and helpful) first, and describe your issue, and inquire if switching to iCab Mobile might solve the refresh problem.
