Usually residental / 4G proxies help. But if your account lost 'trust score' then you have to keep uploading videos instead of photos (it's an option in Jarvee) and after some time (1 week - 2 months) it will be ok.
But I'm not sure if that's the case this time. I've been having this issue for the new accounts about 3 months ago and it took me about 15-70 days of uplaoding videos to solve this (it depends on the account), but I've never had a problem with my old accounts that I was running for 5-6 months already. and 4 days ago 28 out of my 29 accounts started having this problem now, so I think it's something more serious right now.
So now we have to check if resting your accounts will help, (few users wrote that they'll do it in this thread so we'll wait for their updates) and I'll test videos method and update it as soon as one of accounts will be able to upload photos again.
Btw, if you use the same hashtags over and over again then instagram deletes your description or you get shadow banned, but it doesn't delete your posts.
That's not the case. My accounts never like and I have the same problem. (In my case it started 28.02-01.03)
