You can add an extension called IG Helper to your browser. With that, you can get infinite scrolling, and load every GAs on the same page (also filter them).
IG Helper doesn't work on Firefox anymore. Besides, back when it did work on Firefox I remember that if IG giveaways glitched out then endless scrolling would stop adding new giveaways and you'd still have to refresh the page. So you'd have to start over from the beginning anyway even with endless scrolling on. And then you'd have to figure out how far in the scrolling you were before you had to refresh. It wasn't any better of an experience to have endless scrolling when the giveaways section kept failing, imo.
The only real fix is for IG to allow you to go back to a specific page number on the giveaways section.
IG please allow us to go to a specific page number in the giveaways section again!
It's infuriating at this point to have to keep going back to the start when giveaways fail to load. And it's even worse because this very, very, very useful function used to be part of the giveaways section. Why did IG take useful functionality out in the first place?
When the giveaways section keeps failing, being able to go to a specific page on the giveaways section in not just useful, it's
necessary.
