My Update:
 Salary Account with ICICI
Existing ICICI Credit Cards 
(All LTF) in Order of Approval:
- Platinum (my first ICICI card)
 
- Amazon
 
- Coral Rupay (obtained by changing SIM to an Android phone, thanks to the TF community)
 
- Sapphiro Dual (approved in March 2024 via RM)
 
- Rubyx Visa LTF (upgraded from Platinum via Twitter/customer care immediately after Sapphiro approval)
 
After checking for upgrades in the mobile app and net banking, I found an MMT card with JF & 0 AF and a Rubyx Visa paid card, (even though I already had an LTF Rubyx). Hoping for an 
LTF Emerald card, I swapped my 
SIM to an Android phone but was offered an 
LTF Rubyx Dual card instead. Despite feeling like a downgrade, I applied for the LTF Rubyx Dual card, which I can now see virtually in the mobile app.
