I agree, quite annoying. I had to play around with my retrieval settings with the email settings. Go to your email app and open it. Go to the three ellipsis lines (upper left hand corner), go to the gear wheel for settings, then select your email account, scroll down to retrieval size limit and select it. I did end up changing it to unlimited. It's not ideal for people who have restricted data, but was so annoyed with having to click again and again like the frustration you shared. You could try bumping out to 100k and so forth first if you don't want to select unlimited. Hope this helps.
