Animation issue when resized

Hello. I made an animation (gif) in aseprite and posted it on social media, but the quality of the animation was lower compared to what it really is, so I decided to increase the resolution of the animation, so it would has a better quality. I resized it from 200x200 (1000% when export) to 720x720 - I changed the sprite size - (also 1000% when export). The quality has really increased, the animation works equally but with higher quality. But when I share the file, even though it is a .gif, it stops animating, it only animates by opening the file directly, but it does not animate when I post or share it via message. To solve the problem of stopping animating, I decided to go back to the previous resolution, as it stopped animating when I changed the resolution to 720. But that didn’t work either, I went back to 200x200 and the drawing was blurry, crooked, disjointed, in addition to continuing to not animate. Since going back to 200x200 didn’t help, I tried going back to 720 but it bent even more. I would like to know what to do to make the animation work when I put it at 720x720 and how I can resize it again without going everything wrong. Thank you in advance.
