... I only see those additional options when I log in as myself, but NOT when I log in as my wife ...
I think that only Immigration can solve your problem , because evisa.imigrasi.go.id is decreasing the process options of the sponsor's account , similar to Roytoh's case at
https://www.expatindo.org/community/threads/passport-mutation-aka-change-of-passport-number.8228/ .
Note : My guess is that you two (holders of sponsored Stay Permits) accessed your Stay Permit's data from your personal evisa account (when you were not supposed to) , making the Immigration system to cause a problem to the sponsor's evisa account .
Unfortunately Roytoh didn't tell how he solved the problem . But another less similar problem happened with Balikbob at
https://www.expatindo.org/community...sored-by-indonesian-spouse-how-i-did-it.8157/ , and he/she solved by sending an authorization letter to Immigration (as per the local Immigration office) + later going to the Immigration Directorate in Jakarta .
From his/her post no.11 : "... Finally after 3 months of emails and visit to Immigration office in South Jakarta we got my KITAS linked to my wifes account, First we went to Kantor immigrasi Jaksel and they gave us a sample letter my wife had to complete and an an email adress to send to at main office Kuningan. 2 weeks later we get reply with another email attache and told to send it to that email address, we did that and got no reply, wife sent email every week for the last 2 + months, no response, finally we went to Head office in Kuningan yesterday, (hard place to get into), Satpam took us to a small annex to the left of the main office where BNI bank is and there is a row of desks with immigration staff, (not in uniform), who were very nice and sorted the problem in 30 minutes, what they did was cut off agent's access to the account, which they had full control off but was in my wife's name and reassigned it to my wife by opening her a new sponsor's account using another email address my wife has.
They said no need for agents anymore and if we have any further problems then to go straight back to them for assistance, we now have full control of my ITAS and we will start the conversion process to KITAP in the next few days ..." .
